Laser Quantum: Venteon amplification

Laser Quantum exclusively provides comprehensive solutions for the emerging market of OPCPA systems - 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 and thus is ideally suited to support the bandwidth and pulse duration generated by the broadband VENTEON femtosecond systems.

Laser Quantum is capable of all the necessary technology required to realize 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 specialized seed laser system, the Venteon PULSE OPCPAseed, which features a dual laser output for both, ultra-broadband signal and additionally a narrowband pump seed @ 1030 nm. The interface of the narrowband seed can be adapted in terms of coupling (free-space or fiber-coupled), pulse energy (with or without pre-amplification) and filtering. 

For amplifying the narrowband pump pulses @ 1030nm we have developed an independent preamplifer solution. TheVenteon PULSE Preamplifier modules are designed for  amplifying low energy pulses (10 pJ) of the seed oscillator to significant higher power levels. All modules can of course be used as independent amplification modules for other laser systems around 1µm.

Using this unique front-end laser system, the Venteon PULSE OPCPA is the first complete commercial protoype OPCPA system that now allows for the generation of sub-8fs pulses with pulse energies of more than 5µJ at high repetition rates.

With the Venteon PULSE 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.
