The authors report recent progress on diode laser frequency stabilization emitting near 850 nm. A confocal Fabry-Perot cavity is used to feedback the beam from the diode laser and provide resonant optical stabilization of the semiconductor laser. They present a detailed theoretical analysis of the static and dynamic frequency noise power spectrum of the coupled cavity laser field. Experimentally, they achieve static frequency noise reduction of 50-60- dB and obtain a dramatic reduction of the laser linewidth from 20 MHz to less than 4 kHz. Finally, a detailed analysis of the beat-note spectra of two optically self-locked diode lasers shows a non-Lorentzian RF power spectrum.
