Green laser generating apparatus and optical engine system using green laser generating apparatus

摘要

A green light generating apparatus and an optical engine system using the same for increasing duty ratio about laser source are provided to increase green light conversion efficiency and increase operation temperature of the green light generating apparatus by using a heater. A laser source unit(204) generates the source laser of infrared ray. A green light output unit(208) converts the source laser wavelength into the green light wavelength which is the short wavelength. The green light output unit generates the green light by converting laser wavelength. A heater unit(210) is the operating temperature about the source laser. A pumping unit pumps the wavelength of the source laser.
