Abstract
The frequency of a 700-mW monolithic nonplanar Nd:YAG ring laser (NPRO) dep ends, with a large coupling coefficient (megahertz per milliwatt), on the p ower of its laser-diode pump source. Using this effect, we demonstrate freq uency stabilization of a NPRO to a frequency reference by feeding back to t he current of its pump diodes. We achieved an error-point frequency noise s maller than 1 mHz/root Hz and, simultaneously, a reduction of the power noi se of the NPRO by 10 dB without an additional power-stabilization feedback system.
