Title:
WAVELENGTH CONVERTING DEVICE AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/044673
Kind Code:
A1
Abstract:
A wavelength converting device is provided with a laser resonator; a first wavelength
converting element for converting a fundamental wave outputted from the laser
resonator into a higher harmonic wave; a first temperature control element for
controlling the temperature of the first wavelength converting element; a second
wavelength converting element for converting a fundamental wave outputted
from the first wavelength converting element into a higher harmonic wave; a second
temperature control element for controlling the temperature of the second wavelength
converting element; a first detecting section for detecting the output of the
higher harmonic wave outputted from the first wavelength converting element;
a second detecting section for detecting the output of the higher harmonic wave
outputted from the second wavelength converting element; and a controller for
controlling the temperature control of the first wavelength converting element
by the first temperature control element, the temperature control of the second
wavelength converting element by the second temperature control element, and
current value control of a drive current to be applied to the laser light source.
