Abstract

PURPOSE:To obtain the laser which can oscillate at an ordinary temperature in the visible region, by using the single crystal of zinc sulfide having luminescence of a yellow orangee color as an acting material, using an Ar laser having an oscillating line of 488mum as an excitation source, and providing a wavelength selecting element together with a resonator of an external mirror. CONSTITUTION:Excitation light 2 from the Ar laser 1 having the oscillating line of 488mum is irradiated to the single crystal of zinc sulfide 4 via a two-color mirror 3. Emitted light 5 of the single crystal 4 is completely reflected by the mirror 3. In this constitution, 0.01mol% or more lead is included into the single crystal as an active material, and the light of yellow orange is generated. Then, said light 5 is reflected by a two-color mirror 6, and oscillated light 8 is taken out of the wavelength selecting element such as a diffraction grating 7 and the like as an output. Since the single crystal of zinc sulfide is used as the active material, the variable wavelength laser which oscillates at an ordinary temperature in the visible region can be obtained.
