OPCPA – An explanation and an animation


Laser pulse amplification has for a long time relied upon multi-pass concepts through inverted gain media with limited bandwidth. This concept allows high energy pulses, but due to band narrowing effects and thermal load, the pulses have a long duration and low repetition rates.

Optical parametric chirped pulsed amplification has the advantage of a single pass, employing a high gain and ultrabroad amplification process, therefore maintaining its bandwidth and the associated short pulse duration. The instantaneous nature of the parametric process with no energy storage in the crystal allows for a repetition rate in the order of hundreds of kilohertz without having to deal with thermal lensing.

A wide range of nonlinear applications such as High Harmonic Generation benefit from the photon flux with highly intense few-cycle pulses with ultrabroadband spectrum. Here, the innovative Laser Quantum OPCPA is the ideally-suited light source.

To explain the principles of OPCPA, we have created an educational animation that explains how it works.
