Abstract: PURPOSE: To obtain high power by a method, wherein this device comprises a cladding layer having a refractive index lower than that of an active gain layer and for pumping the active gain layer, a shielding layer provided along each longitudinal edge of the active gain layer, antireflection coating and an optical absorptive medium. CONSTITUTION: This device has an elongated active gain layer G, nipped between cladding layers 14 and 17 for pumping a gain layer, and layers 19, 21 having a lower refractive index than the active gain layer G are formed along each longitudinal edge of the active gain layer G for restricting angular emanation of output light beams to a minimum. Further, an antireflection coating layer AR to a transparent window W at an output end part of the active gain layer G restricts feedback to the active gain layer G to a minimum, and a light absorptive medium at an end part of the active gain layer G remote from the window W absorbs radiations propagation apart from the output end part, and this suppresses the oscillations of laser. Thus, a high power can be obtained.
