Generation of high peak power pulse using 2 stage erbium-doped fiber amplifier
Generation of high peak power pulse using two stage erbium-doped fiber amplifier
This thesis presents the results obtained from generation of high repetition rate, high power output pulse using an erbium-doped fiber amplifier (EDFA). Two stage amplification was employed. The first stage setup used 980nm pump laser to pump erbium-doped fiber. For the second stage, two 1480nm pump lasers were used to pump erbium-doped fiber in both forward and backward propagating direction. The signal laser was modulated to produce pulses with high repetition rate high peak power. The first stage produced pulse peak power of 2.52W. The overall output peak power, which is produced by the first and second stage, is 16W.
