Abstract
Nanosecond pulses are efficiently amplified by a two-stage EDFA. The EDFA employs an optical bandpass filter between stages to remove the amplified spontaneous emission of the first EDFA that strongly saturates the gain of the second EDFA. The peak power of the amplified output pulse is 83 W when that of the input pulse of 10 ㎱width and 100 $mutextrm{s}$ period is 1 ㎽.
