First experimental results towards a 100 W wavelength tunable femtosecond OPCPA

Abstract

Optical parametric chirped-pulse amplification (OPCPA) is the most promising method for providing compact, wavelength-tunable, high power, femtosecond lasers. We have recently achieved a 112 W OPCPA with wavelength-tunability around 800 nm and 30 fs pulse duration in burst mode (100 kHz in a 800 µs burst at 10 Hz). In this work, we discuss the various laser architectures and the critical parameters in achieving similar laser parameters but in continuous operation.
