Abstract
An optical amplification device includes: a laser medium that amplifies input light to generate output light; an excitation light source that supplies excitation light used for amplifying the input light, to the laser medium; a resonator that includes a pair of first optical elements and disposed to optically face each other with the laser medium interposed between the first optical elements and that resonates generated light generated in the laser medium through the supply of the excitation light; and an optical switch disposed on an optical path of the resonator between the pair of first optical elements.
