A simple design for a quasi-three-level diode-pumped tunable unidirectional
traveling-wave Nd:YAG laser operating at 946 nm is demonstrated using a ca
vity consisting of two intracavity components, a Nd:YAG gain medium, and a
KTP crystal. 280 GHz of tuning up to 160 mW of single-frequency output has
been obtained by inserting a temperature controlled birefringent filter int
o the cavity. (C) 2001 Published by Elsevier Science B.V.
