ABSTRACT:
A diode laser excitation sold-state laser amplifier capable of withstanding a mechanical disturbance, is easily fabricated and adjusted, can stably generate a high-efficiency high-quality laser beam and easily realize a large output. A diode laser excitation solid-state laser using this amplifier, including: a solid-state laser rod extending along the optical axis of a laser beam and including an active medium therein; two side plates for supporting both ends of the solid-state laser rod respectively; a flow tube provided to enclose the solid-state laser rod and containing a cooling medium; a plurality of excitation modules each having a flat substrate, with a hole formed at the center thereof through which the solid-state laser rod is passed, and at least one excitation light source, for providing excitation light from the lateral of the solid-state laser rod; and connecting and fixing means and for connecting a plurality of the excitation modules to each other and fixing them to the side plates.
