Title: Light wavelength converter
Inventor: KATO TAKAYUKI
IPC: G02F1/361
Filed: 1990-03-14
Abstract: PURPOSE:To maintain wavelength conversion efficiency and the incidence coupling efficiency of a fundamental wave high by charging an inert medium in a hermetically sealed container which houses a light wavelength converting element, and has a transparent window for transmitting the fundamental wave and a transparent window for transmitting a wavelength-converted wave. CONSTITUTION:The inert medium 21 is charged in the sealed container 20 which contains the light wavelength converting element 10, and has the transparent window 27 for transmitting the fundamental wave 15 and the transparent window 28 for transmitting the wavelength-converted wave 15''. Then when gas is used as the inert medium, the incident fundamental wave is prevented from shifting in convergence position owing to temperature variation and the wavelength-converted wave is prevented from being disabled to be converted in a small spot owing to the distortion of the wave front of the wavelength- converted wave. Consequently, the sublimation or variation of an organic nonlinear optical material can securely be precluded to prevent the fundamental wave from decreasing in incidence coupling efficiency, thereby maintaining the wavelength conversion efficiency of the light wavelength converting element high.
