Abstract
Narrowing of the linewidth of a diode laser was achieved by an externa l high-Q microcavity, which was a fused silica sphere 370 mu m in diam eter. Coupling of the radiation in and out, and matching to a 'whisper ing gallery' mode of this sphere, were ensured by the method of frustr ated total internal reflection. Optical feedback was provided by the R ayleigh scattering. The width of the beat-note spectra of the investig ated and reference lasers did not exceed 100 kHz.
