Tunable, continuous-wave neodymium-doped monomode-fiber laser operating at 0.900-0.945 and 1.070-1.135 microm

A tunable Nd(3+)-doped monomode-fiber laser has been constructed that operates continuously at room temperature. The tuning range covered is 0.900-0.945 and 1.070-1.135 microm. Output powers of 3 mW for 53 mW of absorbed pump and 2 mW for 35 mW of absorbed pump, respectively, were achieved for the two ranges from pumping by a dye laser operating at 590 nm.
