Abstract
PURPOSE:To enable to sufficiently supply optical beam energy to the objective substance having a high reflection factor by a method wherein the laser beam emitted from a laser body is irradiated to the objective substance through a collimeter lens, a polarized light beam splitter, a quarter-wave plate and a beam condensing lens, and a reflector beam of light is splitted by a splitter and then received by a mirror. CONSTITUTION:A resonator 2 is constituted by the semiconductor laser body 1 and the laser beams irradiated from this resonator 2 are formed into paralleled beams of light using the collimeter lens 3. Then, said beams of light are irradiated on the objective substance by the beam condensing lens 4. In this constitution, the optical isolator consisting of the polarized light beam splitter 6 and the quarter-wave plate 7 is provided in between lenses 3 and 4 and at the same time, a plane mirror 8 is formed on the opposite side of the splitter 6. Through these procedures, the light totally reflected by the splitter 6 is reflected by the plane mirror 8 and it is irradiated to the objective substrate again as a recurred light, thereby enabling to supply almost twice the optical beam energy for the objective substance 5.
