Abstract

PURPOSE:To increase the convertible wavelength range by setting the center of rotation of a nonlinear crystal fixed on a rotary table so that a laser beam is passed through the point of symmetry of the crystal at the time of the maximum rotation of the crystal. CONSTITUTION:When a nonlinear optical crystal 2 made of LiNbO3 crystal is fixed on a rotary table 3, and dye laser beams with variable wavelengths oscillating at 0.58-0.84mum and YAG laser beams oscillating at 1.06mum are allowed to enter the crystal 2 to take the beat, in the case where the crystal 2 is a 60 deg. cut crystal, the crystal 2 has + or -30 deg. maximum angle of rotation. The center line 1a of the laser beams 1 is passed through the point 4 of symmetry of the crystal 2 to the angle of rotation, and the intersection 5 of the extension 1b of the center line 1a of the incident beams and the central axis 1c of the crystal is determined to be the center of rotation. Thus, the convertible wavelength range is increased.
