Abstract
In the first period from pumping start time Tto time Tin a laser light sourcethe power of pumping light Loutputted from a pumping light sourceso as to irradiate a laser mediumis at value Pwhereas the power of light Lincident on a saturable absorberafter being emitted from the laser mediumis at an absorption saturation threshold or lower, which causes a resonatorto lower its Q-value, thereby suppressing the laser oscillation. Immediately before time Tthe power of light Lis slightly lower than the absorption saturation threshold. In the second period subsequent to the first period, the power of light Lis at value Pgreater than the above-mentioned value Pwhereas the power of light Lexceeds the absorption saturation threshold, which causes the resonatorto increase its Q-value, whereby a mirroroutputs pulse laser light Lto the outside.
