Author Affiliations +
A frequency-converted optically pumped semiconductor laser (OPSL) is described. The 976-nm OPSL is frequency doubled intracavity and is forced to operate in single longitudinal mode. An external resonator, containing a cesium lithium borate crystal is locked to the 488-nm fundamental, generating the second harmonic at 244 nm. Continuous wave output in excess of 200 mW is generated.
