Abstract
The combination of diode-pumped cw single-frequency Nd:YAG lasers and monolithic resonant frequency-doublers has lead to highly efficient and compact 532nm sources [1,2]. Using a diode-pumped 700 mW Nd:YAG laser, we have generated 500 mW of 532nm second harmonic with a monolithic magnesium-oxide-doped lithium niobate frequency-doubler. This corresponds to a conversion efficiency from 1064nm to 532nm of 72% and a conversion efficiency from the 2 W of 808.5nm diode pump light to the green of 25%.
