CPA-Free High Repetition Rate Few-Cycle OPCPA

Optical Parametric Chirped-Pulse Amplification (OPCPA) systems have developed into a key-enabling light source providing high energies at high repetition rates and covering a wide range of wavelength regimes from the visible to the mid-infrared with few cycle pulse durations [1]. However, most systems are complex to operate and rather bulky due to large fiber or regenerative amplifiers used as a pump source. The additional need for a stretcher and compressor in the pump laser adds complexity, timing jitter and reduces the overall optical-to-optical efficiency. In this work, we present a novel approach that allows a high repetition rate, few-cycle OPCPA system based on a compact and CPA free solid-state amplifier system.
