Abstract

40 mW of dual-frequency power from a microchip diode-pumped solid-state Nd:YAG laser is presented. A coupled cavity is used as a mode selector and enforce a single frequency oscillation. An electro-optic crystal and a pair of quarter-wave plates are used to obtain dual frequency oscillation, respectively. By changing the applied voltage and the angle between two fast axes of the wave plates, the frequency difference of the two frequency is changed. Using dual quarter-wave plate method, we obtained 40 mW of dual-frequency laser output when the absorbed pumping power was 690 mW.
