Wavelength selecting method in wavelength tunable laser and wavelength selectable laser oscillator in wavelength tunable laser |
摘要 |
An object of the present invention is to electrically tuned control an oscillating wavelength of a laser at high rate and in good reproducibility without providing any mechanically movable section in the laser resonator. To achieve the object, provided is a laser oscillator comprising a laser resonator composed of a mirror on the output side and a total reflection mirror, a Ti:Al2O3 laser crystal disposed in the laser resonator, an acousto-optic crystal disposed in the laser resonator and to which are inputted the outputting light rays from the Ti:Al2O3 laser crystal, a piezoelectric element mounted on the acousto-optic crystal to input acoustic waves thereto, and a diffraction light ray correcting prism disposed in the laser resonator and for correcting an angle of deflection of the diffraction light rays outputted from the acousto-optic crystal. <IMAGE> |
