WAVELENGTH CONVERSION LASER LIGHT SOURCE AND TWO-DIMENSIONAL IMAGE DISPLAY, LIQUID CRYSTAL DISPLAY, AND LASER LIGHT SOURCE WITH FIBER

摘要

PROBLEM TO BE SOLVED: To solve the problem wherein phase matching temperature (wavelength) changes according to harmonic output and efficient wavelength conversion is disabled because fundamental waves and generated harmonics themselves are absorbed and temperature of an element itself rises depending on types of nonlinear optical crystals used as the wavelength conversion element.;SOLUTION: In a wavelength conversion laser light source, the wavelength conversion element has light absorption characteristics, and holding temperature of the wavelength conversion element is shifted according to the light quantity of fundamental laser light output from a fundamental laser light source.;COPYRIGHT: (C)2011,JPO&INPIT
