This advanced internal software maintains the performance of the output beam, ensure a stable frequency output across long measurements and wide temperature fluctuations. Tests have shown wavelength shifts of less than ±2pm over a 20°C shift in temperature and 0.3pm at constant temperature over a 30-minute test period. This technology eliminates mode drift and hop and creates a narrow line width laser with no sidebands.

                This makes the torus family ideal for such applications as holography, interferometry, Brillouin scattering and any others where measurement time is over extended periods.

                  • Femtosecond

                  • We specialise in femtosecond laser technology with ultra-short pulses, high repetition rates and application based systems that offer unique capabilities and benefits to a wide variety of applications.
                      • CEP stabilised systems

                      • With pulse durations approaching the single cycle limit, the phase relationship between the carrier and its envelope becomes increasingly important. Controlling the carrier envelope phase (CEP) enables the exploration of a whole new area of extreme nonlinear physics where the relationship between the phase of the carrier wave and its envelope becomes crucial to the observed phenomena, e.g. in attosecond physics, where the front end of the machines generating isolated attosecond light pulses traditionally are based on CEP-stabilized oscillators. Another field which has opened up is the exploration of CEP dependent effects in electron emission spectroscopy, or more generally in the field of nano optics, plasmonics and femtosecond electron point sources.
                          • venteon CEP5

                          • The venteon CEP5 laser is a complete carrier-envelope-phase (CEP) stabilised laser system that utilises the exceptional spectral characteristics of the venteon ultra oscillator for a direct realisation of sub-two cycle CEP stable laser pulses with less than 50 as timing jitter. The CEP5 locking approach is the most natural way of locking the CEP by only filtering the spectral wings and is thus efficient and low-noise. Most importantly, it does not affect the properties of the ultrashort output beam by avoiding refractive elements as an AOFS in the beam path.

                          • venteon OPCPA

                          • The venteon OPCPA provides a unique combination of a few-cycle pulse duration with a pulse energy in the µJ-regime at a high repetition rate. The excellent output stability, and the ability for a CEP-stabilised output, makes this amplifier the ideal source for nonlinear spectroscopy, high harmonic generation and applications in attosecond physics. In contrast to more commonly used Ti:sapphire amplifiers, the unique parametric amplification process of the venteon OPCPA gives rise to a much larger gain bandwidth which maintains the excellent few-cycle pulse duration through the amplification process.

                        • Few-Cycle - Short Pulse

                        • Few-cycle, short laser pulses have a number of advantages for researchers. At a constant average power, short pulses have a higher peak power and the higher spectral bandwidth is important for spectroscopy, THz generation and OPCPA seeding application. They also benefit the study of ultrafast processes in such applications as pump-probe or time domain spectroscopy.

                          The Laser Quantum range of short pulse lasers produce the shortest commercially available pulse duration, typically below 5 fs.

As technology evolves, LFCs become more and more attractive for industrial applications where the main requirements, in addition to high precision measurements, are low-maintenance, long-term stability, flexibility and usability.

                            Laser Quantum’s solution to the taccor comb is highly suited for both scientific and industrial purposes. The taccor comb preserves the turn-key operation, long-term stability and low-maintenance of Laser Quantum’s successful 1 GHz femtosecond laser taccor and is thus also attractive for users new to the field of LFC applications. The 1 GHz repetition rate is unique to the market and exceeds the performance of LFCs based on lower repetition rate lasers. The taccor comb benefits from over 15 years of experience in high repetition rate femtosecond laser development and has been used to set world records in the field of optical frequency metrology.

                                • Photonics Essentials

                                • Laser Quantum understand that any photonics laboratory working with ultrafast lasers needs a specialist set of equipment to make best usage of the laser beams. Mirrors to reflect and shape, wedges to control group velocity dispersion and beam splitters for dividing beams, plus the mounts and periscopes needed to direct it to the application or fibre coupling the laser directly to the experiment.
                                    • Pulse Management

                                    • The generation of ultrashort pulses or a high repetition rate pulse train is only part of the challenge when using femtosecond lasers. The laser pulse train needs to be controlled and monitored to ensure the correct characteristics for any application.

                                      Laser Quantum support pulse management with a range of products that allow monitoring, shaping and timing of laser pulses exiting the aperture.

                                      • HarmoniXX SHG - Manufactured by A·P·E Angewandte Physik & Elektronik GmbH, the HarmoniXX is a second harmonic generator tested to ensure optimum performance with the taccor lasers
                                      • TL-1000 - This system provides repetition rate locking when referenced to an external signal, e.g. another laser or an RF generator
                                      • TL-1000-ASOPS - A frequency offset timing unit that locks two pulse trains with a frequency difference of up to 20 kHz
                                      • venteon SPIDER - This system allows you to easily measure the pulse durations and spectral phase and is capable of handling sub-5 fs pulses with octave-spanning spectrum

                                        • THz Technology

                                        • THz radiation is a fast growing area of research due to its non-ionising nature and transparency to many materials. Combined with time domain spectroscopy, it can provide information on the samples effect on amplitude and phase of the radiation, thereby providing more information than other spectroscopic techniques.

                                          The HASSP-THz is a fully configured pump-probe Asynchronous Optical Sampling instrument that instead of using mechanical translation stages to form the time delay between pump and probe pulses, uses two pulse trains with a slightly offset repetition rate. This greatly improves the resolution of any experiment.

                                            • venteon Amplification

                                            • aser Quantum exclusively provides comprehensive solutions for the emerging market of OPCPA technology - the most direct approach for amplified high-power, few-cycle femtosecond laser pulses. Unlike for other commonly used amplification concepts such as Ti:sapphire-based multipass or regenerative amplifier systems, the parametric amplification process of Optical Parametric Chirped Pulse Amplifiers (OPCPA) features a much larger gain bandwidth and no gain narrowing; thus is ideally suited to support the bandwidth and pulse duration generated by the broadband venteon femtosecond oscillators directly from the amplification process. Laser Quantum provides the only commercially available OPCPA product offering MHz repetition rate at microjoule pulse energy and sub-8 fs, with complete CEP stabilization available.

                                              Laser Quantum is capable of all the necessary technology required to realise a complete OPCPA system and proved its expertise, knowledge and competence by developing the world’s first commercial OPCPA.

                                              As a solid basis of the OPCPA systems, we can provide a specialised seed laser system, the venteon dual, which features a dual laser output for both ultra-broadband signal and for optical synchronization of the amplifier pump, a narrowband seed @ 1030 nm, resulting in low timing jitter. The interface of the narrowband seed can be adapted in terms of coupling (free-space or fibre-coupled), pulse energy (with or without pre-amplification) and filtering.

                                              For amplifying the narrowband pump pulses @ 1030 nm we have developed an independent OPCPA pump amplifier module all implemented in fibre technology (up to the compressor) with high overall efficiency and a high degree of integration at a very compact form factor. Fitted with interlocks and internal diagnostics for status of the system, active power stabilization and a one-button start function operated from within the control electronics. The pre-amplifier inside this unit is fitted with two pulse pickers for high pulse contrast. Being completely fibre-based and thus alignment free, it enables flexibility in delivered repetition rate, long term stability and a high degree of integration at a very compact form factor.

                                              For best recompression of the amplified broadband pulses from the seed oscillator, sophisticated dispersion management is implemented to match the higher order dispersion of the compression gratings (behind the main amplifier) to the fibre Bragg grating based stretcher allowing for sub-8 fs pulses from the amplifier.

                                              Parts of the preamplifer are offered as an independent solution. The venteon preamplifier modules are designed for amplifying low energy pulses (10 pJ) of the seed oscillator to significantly higher power levels. The venteon pre-amp can be used as independent amplification module for other laser systems around 1 µm.

                                              With the venteon SPIDER and the octave-spanning compression mirrors, Laser Quantum can also supply the pulse compressing and accurate measurement of few-cycle pulses generated by OPCPA systems.
