2.92 µm Cr2+:CdSe single crystal laser pumped by a repetitively pulsed Tm3+:Lu2O3 ceramics laser at 2.066 µm

Abstract

A laser oscillator based on Cr2+:CdSe single crystal pumped by 2.066 µm radiation of a Tm3+:Lu2O3 ceramic laser was created and investigated. Repetitively pulsed oscillations at a wavelength of 2.92 µm with a bandwidth of 80 nm were demonstrated. The output power was up to 350 mW at 10 kHz repetition rate with a pulse duration of ~200 ns in the good-quality beam.
