<p><P>PROBLEM TO BE SOLVED: To provide a laser device capable of outputting pulse light beams differing in pulse width selectively and coaxially. <P>SOLUTION: The laser device 1 includes a resonator 10, an excitation energy supply part 20, a seed light source 30, a seed light introduction part 40, etc. The resonator 10 includes a laser medium 11, a transparent medium 12, and an optical input/output part 13. When introduction of pulse seed light output from the seed light source 30 into the resonator 10 is set by the seed light introduction part 40, reproducing amplification operation is performed in which optically amplified pulse light is output by the optical input/output part 13 to outside the resonator 10 after pulse seed light introduced onto a resonance optical path by the optical input/output part 13 is optically amplified by the laser medium 11. When non-introduction of the pulse seed light output from the seed light source 30 into the resonator 10 is set by the seed light introduction part 40, cavity dumping oscillation operation is performed in which the pulse light optically amplified by the laser medium 11 is output by the optical input/output part 13 to outside the resonator 10. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
