Abstract
We present results for continuous-wave second-harmonic generation of 532 nm light in an external cavity locked using a spatial mode interference techn ique. This technique does not require frequency modulation and thus yields a clean second-harmonic spectrum devoid of modulation sidebands. The perfor mance is compared with the same system controlled by Pound-Drever-Hall lock ing. Both techniques achieved the same maximum output power with comparable stability which is predominantly limited by fluctuations in the pump power and the nonlinear crystal temperature.
