<P>PROBLEM TO BE SOLVED: To provide a Q-switch laser light-emitting apparatus which can be small-sized while extending a pulse width of a Q-switch laser without enlarging a physical length of a resonator. <P>SOLUTION: Between a total reflecting mirror 13 and an output mirror 14, an electro-optical Q-switch element 11, a high refractive index material member 10 and a solid-state laser medium 12 are disposed in this order from the total reflecting mirror 13 toward the output mirror 14. Since both end faces 18a, 18b of the solid-state laser medium 12 on an optical axis are tilted at a Brewster angle with respect to the optical axis, laser light emitted from the solid-state laser medium 12 is not randomly polarized light but becomes linearly polarized light. Furthermore, since the high refractive index material member 10 is provided, an optical length of an optical path becomes short. <P>COPYRIGHT: (C)2012,JPO&INPIT |
