Abstract
PURPOSE:To prevent invasion and contamination of a semiconductor laser device by dusts by a construction wherein, within a closed space defined by closure members such as a cap, base or the like, a path of beam between a laser element and optical window is formed as the second closed space. CONSTITUTION:A resilient heat insulating material 2 is disposed inside of a metallic cap 3. The heat insulating material 2 has a cylindrical form with cavities of diameters D1, D2, as well as a conical cavity corresponding to an optic window. A slit for receiving terminal members 5a, 5b of the laser structure is formed in a portion of the heat insulating material, at a right angle to the base. The path of beam from the laser element 4 to the window 1 is thus closed completely and, accordingly, free from contamination by dusts. The scrubbing of the pellet element during assembling of the device, as well as cleaning after soldering, is unnecessary.
