PHASE-MATCHED UV GENERATION AT 0.1774 MU-M IN KB5O8-CENTER-DOT-4H(2)O

摘要

Sixth-harmonic generation of the Nd:YAG laser frequency at 1.0642 mu m has been achieved in KB5O8 . 4H(2)O by type-1 mixing the fundamental and fifth harmonic at room temperature. The phase-matching angles were measured to be (theta = 90 degrees, phi = 68.5 +/- 0.5 degrees) and (theta = 80.0 +/- 0.5 degrees, phi = 90 degrees) in the x-y and y-z planes, respectively. Improved Sellmeier equations of this crystal are presented. (C) 1996 Optical Society of America [References: 20]
