OPTICAL FIBER LASER

摘要

PROBLEM TO BE SOLVED: To provide an optical fiber laser generating Terahertz wave.

SOLUTION: A laser includes: a laser light source 30 generating a laser beam due to the excitation of a pump light source 34; a first resonator 10 and a second resonator 20 resonating the laser beam at first and second wavelengths; and a coupler 40 separating and supplying the laser beam emitted from the laser light source 30 to the first resonator 10 and the second resonator 20 and feeding back the laser beam having the first and second wavelengths resonated respectively in the first resonator 10 and the second resonator 20 to the laser light source 30.
