HARMONIC GENERATOR AND IMAGE DISPLAY DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To suppress a local increase of energy density per unit time in a nonlinear crystal. SOLUTION: A fundamental wave 50 emitted from a fundamental wave laser light source 10 is converged by a condenser lens 20 and made incident on a nonlinear crystal 11 having a poled structure. By displacing a converged position of the fundamental wave 50 by a scanning mirror 21, a local increase of energy density per unit time in the nonlinear crystal 11 is suppressed.
