Abstract

PURPOSE:To emit higher harmonic light having the different wavelength, by adjusting the transmitting angle of a nonlinear optical element, which is provided between a laser discharge part and the output mirror of resonant mirrors. CONSTITUTION:A nonlinear optical element 15 is located between a down collimator 14 and an output mirror 13 on the optical path of reduced parallel light L1. The optical element 15 is mounted on an angle adjusting stage 16. For the nonlinear optical element 15, e.g., beta-BaB2B4 (beta barium borate) is used. A total reflecting mirror 12 and the output mirror 13 have the total reflecting characteristic of the oscillating lights of 510.6nm and 578.2nm of a copper vapor laser. The second higher harmonic of said two wavelengths is approximately totally reflected by the total reflection mirror 12. The output mirror 13 makes the reflectivity as low as possible. When the angle adjusting stage 16 is adjusted so that said one oscillating light matches, e.g., the wavelength of 510.6nm, laser light L2 having the wavelength of 255.3nm is outputted from the output mirror 13 as the second harmonic.
