Solid-state laser device with optical fiber cable connection
First Claim
1. A solid-state laser device comprising:
- a solid-state laser device main body incorporating a semiconductor laser and a first optical system for shaping a first laser beam emitted from said semiconductor laser;
an optical fiber cable connected to said solid-state laser device main body and accommodating an optical fiber for guiding the first laser beam shaped by said first optical system; and
a solid-state laser medium which is incorporated in a distal end portion, at a light exit side, of said optical fiber cable, and generates a second laser beam by pumping the first laser beam, wherein said first laser beam has a wavelength which easily passes through said optical fiber, and said second laser beam has an infrared wavelength which can hardly pass through said optical fiber.
