All-fiberized, mode-locked laser at 1.95 mu m using copper chalcogenide Cu2Te-based evanescent field interaction

For the first time, a copper telluride (Cu2Te) based saturable absorber (SA) was demonstrated for mode-locking in a thulium-doped fiber laser. Layers of Cu2Te were deposited onto a side polished fiber (SPF) using the optical deposition technique, forming an all-fiber SA device. The nonlinear optical...
