Tunable Parametric Light Generator with a Spectral Line Width of Generation of 1 cm–1 Based on a ZnGeP2 Monocrystal
摘要
Abstract
A parametric light oscillator based on a ZGP single crystal pumped by Ho:YAG laser radiation was created, which generates radiation according to type II synchronism with smooth tuning in the spectral generation range with a width of the generated radiation of 1 cm–1 due to the use of intracavity radiation selection using a Lyot filter. The pulse energy of the generated radiation was 0.08 mJ at a pulse repetition rate of 10 kHz and a pulse duration of 26 ns. The tuning range was from 3.3 to 4.2 μm. The divergence of the generated radiation did not exceed 1.5 mrad.
