Abstract
A pulse fiber laser devicehas a Fabry-Perot type optical resonator, and is provided with an excitation light source, an optical coupling unit, an amplifying optical fiber, a saturable absorber, a gradient index lens, an optical output unit, a dispersion adjusting unit, a mirrorand a mirror. The saturable absorberand the mirror, integrated into one body, constitute a saturable absorber mirror. The gradient index lensconverges the light output from an end face of an optical fiberand outputs the light to the saturable absorber mirror, and inputs the light reflected from the saturable absorber mirrorinto the end face of the optical fiber. Thus, there is provided a pulse fiber laser device that enables easy adjustment of the intensity of light incident on a saturable absorber and facilitates miniaturization.
