Abstract :
Summary form only given. The physical robustness of the GdCOB family of nonlinear crystals has attracted interest in these materials in applications involving high-average power. Large crystal growth of these materials is relatively easy, they readily and quickly accept a high quality optical polish, and are non-hygroscopic. High average power conditions encountered in intracavity frequency conversion makes desirable an intracavity converter crystal that has low angular and temperature sensitivities. We report values of the thermal sensitivity, /spl beta//sub T/=(/spl delta//spl Delta/k//spl delta/T), and angular sensitivity, /spl beta//sub /spl theta//=(/spl delta//spl Delta/k//spl delta//spl theta/), for LBO, GdCOB, and LaCOB as determined from experiment.
