  • Passive Q-switch-type solid laser apparatus
    Patent number: 8976820
    Abstract: To provide a passive Q-switch-type solid laser apparatus for outputting a high peak-power pulse laser whose pulse energy is large and pulse-time width is small. A passive Q-switch-type solid laser apparatus has: two reflection elements for forming an oscillator; a solid gain medium being disposed between the two reflection elements; a saturable absorber being disposed between the two reflection elements; an excitation device for exciting the solid gain medium; and a cross section control device for making at least one of a stimulated emission cross section of the solid gain medium and an absorption cross section of the saturable absorber closer to another one of them; and the cross section control device is equipped with at least one or both of a temperature control device for retaining the solid gain medium at a predetermined temperature and an oscillatory-wavelength control device for fixating an oscillatory wavelength at a predetermined wavelength.
