Abstract
A laser amplifier includes a planar optical waveguide for laser amplification, and an input optical system for inputting signal light to a core layer of the planar optical waveguide. The input optical system includes: a collimating lens for converting output light from a signal light source into parallel light; an anamorphic prism for reducing the beam width in a first direction of output light from the collimating lens; and a cylindrical lens for collecting output light from the anamorphic prism in a second direction, and output light from the cylindrical lens is input to the core layer.
