OPTICAL OUTPUT MODULE AND OPTICAL PICKUP DEVICE ADOPTING THE SAME

摘要

PURPOSE: An optical output module and an optical pickup device adopting the same are provided to offer a simple structure to regulate beams by using a window protecting the inside of the module from dust. CONSTITUTION: A semiconductor laser(41) irradiates a laser beam of a predetermined frequency by installing on a base(31). A cap(33) surrounds the semiconductor laser. A beam regulating window(45) regulates the transmitted laser beam and partially reflects an incident beam by combining/installing to a predetermined position of the cap matched with an advancing path of the laser beam. A monitor detector(43) installed in the cap monitors the laser beam irradiated from the semiconductor laser by receiving the laser beam reflected from the beam regulating window.
