Conversion of a Chirp Pulse Into the Second Harmonic in a KDP Crystal

Division for Materials Science

Research output: Contribution to journal › Article

Abstract

Results of investigation of conversion of radiation with the wavelength λ = 950 nm and pulse duration of 100 ps into the second harmonic are reported. It is demonstrated that the second harmonic pulse duration is half the pulse duration at the fundamental frequency. The converted radiation linewidth remains unchanged. The beam quality factor М ² increases from 1.16 to 1.56. The maximal conversion efficiency is 12.2%.
