LASER DEVICE AND PRODUCTION THEREOF

摘要

PURPOSE:To eliminate optical precision adjustment so as to realize the cost reduction through mass-production. CONSTITUTION:A solid-state laser material 1 is excited by a semiconductor laser 7 and the excited light is converted into one half of wavelength through a wavelength conversion material 3. The other face of the plate material 1, which is provided with a plane reflecting mirror 2 on one face, is brought into contact with one face of the material 3 which is provided with a reflecting mirror 4. Further hardening flexible adhesive 5 is filled in recessed grooves 6 that are prepared on the outside of laser oscillation for either of the other face of the material 1 and one face of the material 3. In this case, it is desired that the contacting faces of the materials 1 and 3 make a tilt angle of 1 to 10 degrees against the reflecting surfaces of the mirrors 2 and 4.
