Abstract

We report the generation of 1178nm based on cascaded Raman scattering in KTA crystal intracavity pumped by a AO Q-switched Nd:YAG laser. The output power at 1178nm is around 80mW when the diode pump power was 7.6W at 808nm. At the same time, the low-order Stokes waves at 1091nm, 1120nm, 1146nm and visible yellow laser at 573nm (the second harmonic wave of 1146nm) are also detected. The total Stokes output power was 240mW and the yellow laser was 115mW. The power at 1178nm can be increased with output mirrors that are more suitable. The spectra of the generated wavelengths were experimentally analyzed and they accords well with theoretical results.
