Abstract

PURPOSE:To obtain a large powered laser device with a short resonator length by disposing as a resonator a concave mirror at one side of a laser amplifying region and a composite reflecting mirror made of two plane mirrors of V shape at the other side of the region. CONSTITUTION:A glass fine tube 2 is retained in an enclosure 1, and there are arranged a concave mirror 4 at one side of the tube 2 and a composite reflecting mirror 11 having two plane mirrors 12, 13 of V shape intersecting at the edge line 14 at the other side of the tube 2. An anode 5, a cathode 6 and a cathode pin 7 are mounted at the enclosure 1, and a mixture gas of He and Ne is filled airtightly therein. In this structure the edge line 14 is disposed while intersecting on the extension of the central axis of the tube 2, and the angle between the mirrors 12 and 13 is so determined that the light emitted vertically from the mirror 12 again passes the interior of the tube 2 when reflecting on the mirror 4 through the tube 2 and vertically incident to the mirror 13. Thus, the laser modes can be formed by two designated by 15, 16.
