Abstract

In this paper the modulation-free frequency stabilization of laser-diode pumped single frequency solid-state laser was reported. The principle of generating a dispersion-like frequency-discrimination curve using a confocal Fabry-Perot cavity (CFPC) was introduced. In the experiment a LD-pumped 1319 nm monolithic non-planar ring oscillator (NPRO) single frequency Nd: YAG laser was used. With the modulation-free frequency stabilization method, the laser was locked to the resonance frequency of the CFPC, whose jitter frequency was less than ±500 kHz in the time of 30 minutes estimated from the locked error signal.
