Abstract

The amplification and lasing characteristics of the newly developed Thulium-Ytterbium co-doped fiber (TYDF) are investigated. It is obtained that both TYDF amplifier and laser operate at 1950 nm region. The maximum gain of 22.4 dB is obtained for 1942 nm signal when the 980 nm multimode pump power, TYDF length and input signal power are fixed at 1.2 W, 5 m and -20 dBm, respectively. At 5 m long of TYDF, the laser produces two prominent lines at 1960 nm and 1965 nm with peak powers of 2.8 dBm and 3.1 dBm, respectively due to the nonlinear polarization rotation (NPR) effect in the cavity.
