The venteon Laser Technology name is synonymous with the science of few cycle, broadband laser pulses. Used in many areas of physical, biological and chemical research e.g. two photon microscopy, CEP stabilisation applications and pump-probe spectroscopy, the venteon range is characterised byreliable performance with long lifetimes.

The venteon family based around short pulse generation includes members that are designed to meet individual specifcation demands of the researcher. Optimised for Power, bandwidth, CEP or OPCPA seeding the venteon family has the right laser.


Range of Lasers

-       venteon one

The venteon one laser system is a versatile and robust option as an entry level to few cycle ultra-short pulses. Highly compact, it offers a wide spectral bandwidth of over 200nm leading to pulse durations below 8fs with typical values around 6.5fs. It is ideally suited to microscopy, spectroscopy and pump probe experiments that require a reliable, simple, turn-key laser solution for ultra-short pulses with a moderate power.

-       venteon power

The venteon power laser system has been optimised to provide the highest power available from the venteon range of ultra-short pulse lasers. Designed on a water cooled monolithic breadboard for mechanical and temperature stability, the venteon power contains an integrated ultra-low noise finesse pump laser.

The venteon power laser can be supplied with CEP stabilised performance or in a state ready for a CEP upgrade. It can also be equipped with a piezo transducer/stepper motor that allows for resonance free repetition rate locking up to 30kHz to a suitable microwave standard.

-       venteon ultra

The venteon ultra laser system provides unique spectral properties from a monolithic breadboard designed to provide stability for long term operation. With an integrated pump laser, the system delivers >240mW of sub 6fs short pulses with an unrivalled spectral bandwidth ranging from 600-1200nm specified with >400nm @-10dBc.

Due to this octave spanning output spectrum, the venteon ultra can be used for direct CEP stabilisation without any additional spectral broadening. The system can be purchased as a fully CEP stabilised laser, or with the necessary components to allow CEP upgrade at a later date.

-       venteon CEP5

The venteon CEP5 is a fully configured ultra-short pulse carrier envelope phase (CEP) stabilised laser system. Comprising the venteon ultra octave spanning laser, the venteon CEP5 system includes an f-to-2f interferometer for fCEO beat generation and the ultra-low noise finesse pure CEP pump laser featuring CEPLoQ™ technology that enables CEP stabilisation without AOM modulation control and all the electronic controls necessary.

The spectral bandwidth of this laser system supports pulse durations well below 5fs directly from the oscillator. Its octave-spanning output is sufficiently broad for a direct CEP stabilisation of the pulses, realising the f-to-2f beating without any additional spectral broadening by either a PCF or PPLN device. Only 10% of the output power is used by filtering the edges of the output spectrum, leaving more than 220mW for subsequent experiments. This is the most natural, direct and reliable approach for realising a CEP stabilisation without distorting the laser output beam and giving an excellent long-term locking performance.

-       venteon dual

The venteon dual represents the ideal front end for broadband few-cycle Optical Parametric Chirped Pulse Amplifier (OPCPA) applications. The spectral bandwidth of this laser allows for the generation of broadband sub-6 fs pulses as signal for a subsequent NOPA stage and provides additionally sufficient pulse energy (>30 pJ @ 1030nm) for seeding an Yb-based amplifier pump stage. The pulses are delivered by two separate output ports and are intrinsically self-synchronised with ultra-low timing jitter.

The first output provides the broadband signal pulses and a duration <6fs. The pulses can be optionally CEP stabilised with the typical performance of the venteon CEP5 laser systems.

The second output at 1030nm delivers - without any additional broadening - more than 30pJ in a spectral bandwidth of 10nm (FWHM) and is ideally suited as a narrowband seed for pump amplifiers. This output can be optionally ordered pre-amplified, delivering pulses with an energy >1nJ.
