Abstract
Provided is a passively Q-switched element or the like, which enables mode selection without increasing the number of components in a resonator in a Q-switched pulse laser or the like that oscillates in a great number of high-order modes and which is also applicable to a waveguide type laser in which a mode cannot be controlled spatially. By combining a saturable absorber () with a transparent material () which is transparent to a laser oscillation wavelength or the like, a passively Q-switched element having a mode selection function and a passively Q-switched laser device in which a passively Q-switched element has a mode selection function, and a planar waveguide type passively Q-switched element and passively Q-switched laser device are provided.
