Paper Abstract

Potassium titanyl phosphate (KTP) has been used to frequency double the 1.32 micrometers output of a Q-switched Nd:YAG laser. Up to 40 mW of average power at 659 nm was obtained using a conventional intracavity doubling approach. A second intracavity doubling scheme was also demonstrated in which KTP served simultaneously as the frequency doubling crystal and as the substrate for one of the resonator mirrors. Although the second harmonic power using this technique was limited by heating in the crystal, the approach shows promise.
