Abstract:

We discuss optimization of locations for the nonlinear crystal in intracavity generation of second-harmonic radiation and show that optimizing the distance between the nonlinear crystal and the two-wave end mirror in the laser cavity may support nearly a 100% increase in the maximum emission power of the second harmonic. The optimum distance depends on the type of end mirror used. We describe a variety of effects that mask the advantages conferred by the optimum location of the nonlinear crystal when performing experiments on intracavity generation of strong second-harmonic laser radiation. We describe various approaches for experimental determination of the optimal location of the nonlinear crystal in the cavity.

Keywords:

intracavity generation of second-harmonic, phase dispersion, lasers
