Fiber laser oscillator |
摘要 |
<p>A fiber laser oscillator 1 is provided with a pumping light source 30 for emitting pumping beams Lin; beam condensing means (light duct) 50 for condensing the pumping beams Lin emitted from the pumping light source 30; and a laser oscillation optical fiber 10 for receiving the pumping beams Lin condensed by the beam condensing means 50 to generate an output laser beam Lout. The beam condensing means 50 has an incident surface Min for making the pumping beams Lin from the pumping light source 30 incident thereon and an emission surface Mout for emitting the pumping beams Lin therefrom. The emission surface Mout is made smaller in area than the incident surface Min. Further, the area of the emission surface Mout is made to be the same as or smaller than that of one end surface of the laser oscillation optical fiber 10.</p> |
