PURPOSE:To insolate, and detect the one part of an output light, and then to indicate with a lamp, the fact that a laser is continuing to oscillate, and also to indicate a length of oscillating waves. CONSTITUTION:From a resonance apparatus controlled by a laser tube 1, mirrors 2,4, and a prism 3, a output light 5 is taken out, and also its one part is isolated with a reference light 7 and is imputted in a pickup 8. A detection light is amplified 9, and then a lamp 10 is turned on, and then an oscillation is indicated. A knob 12 on an organization with a selectivity of the wave length, containing the prism 3 and the mirror 4 in it, is turned around, and then an output wave length is chosen and a conveyance machanism 13 is intervened, and the lamp 10 is shifted and the wave length is indicated on a scale 14. |
