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.

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.
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.

Laser frequency combs (LFCs) have played a key role in high-precision optical frequency metrology for over a decade and have been used in a variety of applications in fundamental science on the macroscopic scale (e.g. astronomy) and the microscopic scale (e.g. studying optical transitions in atoms). 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.
The taccor comb consists of a powerful 1 GHz turn-key Ti:sapphire laser with a matched dispersion compensation module, super-continuum generation and ultra-stable f-to-2f interferometer. It provides an electrical output signal at the carrier-envelope offset (CEO) frequency with at least 35 dB signal-to-noise ratio in 100 kHz bandwidth. The super-continuum generation fibre coupling is stable for long periods and any long-term variations can be compensated with piezo actuators, controlled via a touch-screen interface. The comb extension can be used in conjunction with the taccor power.

Gigahertz repetition rates can offer many benefits over megahertz lasers in a variety of applications. Mode spacing in frequency combs have better separation and higher powers, two photon microscopists will see equivalent image quality, but have a 5-10 times longer sample viability due to the lower peak power and pump-probe experiments have a greater resolution.
The MHz range is based on meeting the needs of the application by offering different architectures, pulse durations and operations. The self-starting and maintaining mechanism of the gecco takes only the start button and mode locking is achieved within 5 minutes. The venteon range is based on ultra-short pulse durations.
The gecco is a femtosecond laser with an exceptionally robust mechanical design in a sealed housing comprising a proprietary mechanism to self-start, monitor and maintain its mode-locking. It is available in a choice of pulse durations, powers and repetition rates to suit many applications.
"The gecco one works great as a seed laser for our 25 fs kHz amplifier system. We are very happy to have this set-and-forget femtosecond laser delivering reliable and reproducible performance every day."Â

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.
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.
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.
