GREEN LASER GENERATING APPARATUS AND OPTICAL ENGINE SYSTEM USING GREEN LASER GENERATING APPARATUS

摘要

PURPOSE: A green light generating device and an optical engine system thereof are provided to improve initial driving speed and green light conversion efficiency by enhancing operating temperature by multiplying the duty ratio of the green light wavelength. CONSTITUTION: A laser source unit(204) generates an infrared laser source. A green light output unit(208) changes the source laser wavelength to a short green light wavelength. A duty ratio management unit(212) raises the operating temperature of the source laser by increasing the duty ratio of the green light wavelength The duty ratio management unit increases the duty ratio of the green light wavelength more than the sum total of the duty ratio for one or more laser light sources.
