Abstract:The paper is devoted to investigation of adaptive optical delay lines, intended for femtosecond pulse shaping. Experiments were performed in the sub PW laser system, based on optical parametrical chirped pulse amplification. The experimental device has revealed high spectral resolution (0.6 nm at 1250 nm) high efficiency, (70% over a 120 nm spectral width at 1250 nm) and flexibility of seed pulse amplitude control. Proper shaping of the transmission function of adaptive optical delay line allows to double the … Show more
