Abstract
A compact LD pumped intracavity frequency-doubled and frequency-stabilized ring Nd:YAP/KTP laser with high output up to 1.1 W at 540 nm is achieved. In the design of the laser configuration, the anisotropic characteristics of Nd:YAP optical biaxial crystal are taken into account. A quarter-wave plate is placed between the Faraday rotator and the α-cut KTP to ensure the output fundamental wave from KTP in pure linear-polarization paralleling to that of the oscillating laser and unidirectional operation of laser. Due to rigorously temperature controlling on KTP crystals and optimizing design of resonator, the stable single-frequency green output is obtained. The intensity fluctuation is less than ±1.5%, and frequency stability is better than ±550 kHz by means of a standard frequency locking technology with F-P cavity.
