| 1. A laser light source comprising:
a plurality of semiconductor lasers for emitting a plurality of laser beams; and
a hollow waveguide with a liquid sealed therein for propagating the plurality of laser beams; and
a cooling mechanism connected to the waveguide for circulating the liquid sealed in the waveguide and cooling the plurality
of semiconductor lasers,
whereby the plurality of laser beams are emitted from one end face of the waveguide.
