Abstract
A solid-state stimulated Raman scattering (SRS) laser oscillation around the 1.6 µm carbon dioxide absorption lines is demonstrated. The stokes output of the SRS radiation at 1.57 µm is generated from the frequency conversion of the 1.35 µm laser radiation of Nd3+:KGd(WO4)2 (Nd:KGW) in the cavity. The maximum output energy was 13.8 mJ with a repetition rate of 10 Hz, in response to the incident laser pumped from the laser diode to the Nd:KGW. To our knowledge, this result of a 1.57 µm intracavity SRS oscillation at CO2 absorption lines around 1.6 µm is gained for the first time.
