Abstract

PURPOSE:To obtain a laser beam condensing device which is safe and convenient at the time of practical use, by providing a hole in the center part of submirror of a Cassegrain optical system, and leading a light beam which is made incident to the center part, to a thermal absorber. CONSTITUTION:A round hole having the diameter L2 is made in the center part of a submirror 5 of a Cassegrain optical system, a mirror 6 is provided on the reverse side, and an incident luminous flux dissipated from a hole of the center part of a main mirror 1 is led to a calorimeter 7, which can be utilized for the minotor of the quantity of incident light. In this way, a laser beam condensing device which is safe and convenient at the time of practical use is obtained.
