Abstract
PURPOSE:To obtain the third harmonic wave, by arranging a first and a second nonlinear optical elements and an optically active substance on the optical path, and in the order of travelling direction of laser ray emitted from a laser oscillator wherein alexandrite is applied to laser medium. CONSTITUTION:On the optical path of laser ray L emitted from a laser oscillator 1, a first nonlinear optical element 2, an optically active substance 10 composed of quartz, and a second nonlinear optical element 8 are coaxially arranged in order of the travelling direction of the laser ray. When an optical rotary angle between the fundamental wave and the double harmonic wave of the laser ray is 90 degrees for a thickness, the polarization between two perpendicular optical waves is arranged in the same direction, by passing through the optically active quartz. After all, the two perpendicular lights have the same direction of polarization by the effect of rotary polarization. Therefore, the power loss of the treble harmonic wave can be reduced by alexandrite laser.
