Abstract

Second-harmonic radiation of several picowatts from various commercial laser diodes with several milliwatts of output power has been observed at various temperatures from 130 to 310 K. No temperature dependence of the conversion efficiency was observed. The spectral width of the second-harmonic radiation was limited by that of the fundamental radiation. An application of the internal second-harmonic radiation to a spectroscopic light source allowed observation of some absorption lines of potassium and aluminum.
