Studying the Possibility of Compressing a Positively Chirped Pulse after Its Transformation into the Second Harmonic

Аннотация

The possibility of recompressing a positively chirped pulse with a duration of 50 ps to a femtosecond under conditions of the chirping of the fundamental harmonic is examined. The characteristics of a compressor based on diffraction gratings are presented, along with the procedure for adjusting it and the parameters of laser radiation. It is shown how a pulse of second harmonic radiation can be compressed to a duration of 75 fs.
