Paper Abstract

Intracavity second harmonic generation of a passively Q- switched cw Nd:YAG laser is studied. The saturable absorber used was a Cr4+:YAG crystal, and the second harmonic generator was a flux grown KTP crystal. The results were compared to a case of acousto-optic Q-switched case. To allow for a unidirectional second harmonic output beam, a folded laser cavity was constructed. However, due to a partially transmitting mirror in the cavity, two output counter propagating second harmonic beams, were generated. Unexpectedly, 180 degrees out of phase periodic power variations of the two output beams were observed, as a function of the distance from the nonlinear crystal to the mirror.
