Abstract
Chirped pulse amplification was implemented in one of six amplifier chains “Progress” phosphate Nd:glass laser system. Laser system configuration and performance are presented. Formation of 300 ps chirped pulse at 1053 nm with energy up to 1 J is made by using developed starting laser which consists of Nd:YLF oscillator, optical fiber, stretcher and three amplifiers with output aperture 20 mm. The large amplifier chain of the laser system includes three rod amplifiers with the aperture of output rod of 85 mm. Preliminary experiments have been carried out yielding output chirped pulses of up to 55 J and compression them to 1.5 ps by grating compressor.
