Abstract

PURPOSE:For obtaining two laser beams easily without any conpler through selecting a threshold of pumping ray, to make a resonator by setting the laser crystal oscillating two beams with different wavelengths between the two reflectors having an equal reflectivity. CONSTITUTION:A threshold P of the pumping of beam 2 is selected so that formulas (1)-(3) may be set up with the threshold P2 of the beam pumping laser crystal 1 on the oscillation with wavelength lambda1 of a resonator M, the ratio R of the transitional sectional area of laser beam of said crystal 1 that is obtained when wavelengths are lambda1 and lambda2, and the ratio a=Q1/Q2 of the loss of the same. At this time, oscillation beams with with wavelenghs lambda1=lambda2 can be obtained at a time, and led out by either of reflectors G1 and G2. Losses Q1 and Q2 have the relation indicated by Q=F+2alphal with non-resonance per reciprocation of said resonator F, crystal length L and resonance absorption loss coefficient alpha. Thereby, laser oscillation beams with different wavelengths can be obtained easily and efficiently without providing a system with a complicated construction.
