Abstract

PURPOSE:To obtain output laser radiation excellent in characteristics wherein light intensity distribution is uniform, repetition frequency is high, and average output is large, by providing an optical path in an optical resonator system with a reflecting part exhibiting a conical surface for the incident light and the output light of a rod, and making up a constitution wherein the incident light from a rod end surface travels in the rod, while repeating total reflection on the peripheral side surface of the rod. CONSTITUTION:Both end surfaces 11 of a laser medium rod 1 are provided with refracting parts constituted of conical convex surfaces having the same vertical angles whose axial centers coincide with each other. Incident light 7 parallel to the rode axis reaches the end surface of the rod, and is refracted and transmitted by the end surface 11 of the conical convex. In the inside of the rod, this light repeats total reflection on the peripheral side surface 12 of the cylinder type rod 1 as shown in figure, and zigzags in the surface in each radial direction including the center axis. Therefore, the effects of internal temperature of the rod 1 and excited light intensity distribution can be cancelled, and the output laser radiation with uniform light intensity distribution can be obtained.
