Grating pair stretcher
WebOct 10, 2024 · Among the dispersion management elements, the grating pair has the advantage of shortening the cavity length and flexible dispersion adjustment [22,23,24,25]. In this paper, we demonstrate an all PM dispersion-managed mode-locked laser oscillator with a figure-of-9 configuration, which generates 25 kW peak-power pulses at 1.03 μm. WebA grating compressor is set up for the 10-PW front end to obtain 20-TW output. An accurate adjustment method of grating attitude (angular position) is presented, which references the direction...
