1.3 mu m passively Q-switched bismuth doped fiber laser using Nb2C saturable absorber

A tunable passively Q-switched fiber laser operating at 1.3 ism was demonstrated using bismuth-doped fiber (BDF) as the gain medium and using niobium carbide (Nb2C) as the saturable absorber (SA). The Nb2C was prepared using the solution casting method, and then fabricated into a film form for ease...
