ABSTRACT:
In the first period from pumping start time T1to time T2in a laser light source1,the power of pumping light L1outputted from a pumping light source41so as to irradiate a laser medium21is at value P1whereas the power of light L2incident on a saturable absorber30after being emitted from the laser medium21is at an absorption saturation threshold or lower, which causes a resonator10to lower its Q-value, thereby suppressing the laser oscillation. Immediately before time T2,the power of light L2is slightly lower than the absorption saturation threshold. In the second period subsequent to the first period, the power of light L2is at value P2greater than the above-mentioned value P1,whereas the power of light L2exceeds the absorption saturation threshold, which causes the resonator10to increase its Q-value, whereby a mirror12outputs pulse laser light L3to the outside.
