Abstract
A laser oscillation device comprises a light emitting unit for projecting a pump laser beam, a laser medium for absorbing the pump laser beam and for emitting a spontaneous emission light, a saturable absorber for absorbing the spontaneous emission light and for emitting a pulsed light, and a holder for holding the laser medium in a close contact state, wherein a portion of the holder as appressed against at least one surface of the laser medium is made of a metal and the pump laser beam is projected to an edge portion of the laser medium as appressed against the holder.
