Light Conversion introduces a new custom OPCPA system, which provides ultra-short light pulses of up to 100 μJ of energy at up to 100 kHz repetition rate. Our OPCPA technology is based on years of experience in developing and manufacturing of Collinear and Non-Collinear Optical Parametric Amplifiers as well as Femtosecond Lasers, and is able to offer leading solutions, such as passive carrier envelope phase (CEP) stabilization.
Light Conversion (together with partners) introduces new custom OPCPA system, which provides ultra-short light pulses of high energy (up to 45 mJ) and high average power (up to 45 W). Our OPCPA technology is based on years of experience in developing and manufacturing of Collinear and Non-Collinear Optical Parametric Amplifiers as well as Femtosecond Lasers, and is able to offer leading solutions, such as passive carrier envelope phase (CEP) stabilization. High temporal contrast in picosecond time scale is achieved by using the femtosecond PHAROS pump and the seed derived from white-light continuum. PHAROS oscillator has enough bandwidth for direct seeding of high energy picosecond Nd:YAG lasers.
The Laser Quantum 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.
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.
The Laser Quantum Venteon PULSE OPCPA seed laser system represents the ideal front-end for broadband few-cycle OPCPA applications. The spectral bandwidth of this laser allows for the generation of broadband sub-6fs pulses as signal for a subsequent NOPA stage and provides sufficient pulse energy (>30 pJ @ 1030nm) for seeding an Yb-based amplifier pump stage. The pulses are provided by two separate output ports and are intrinsically self-synchronized with ultra-low timing jitter
