Abstract :
Spectral gain hole-burning at lambda /sub 0/=1.53 mu m was observed in an erbium-doped fiber amplifier at temperatures between 4.2 and 77 K. The hole width was found to broaden with temperature for T>or=20 K according to a T/sup 1.73/ law. From the data, the room-temperature homogeneous linewidth associated with the 1.531- mu m transition in the /sup 4/I/sub 13/2/-/sup 4/I/sub 15/2/ laser system was determined to be Delta lambda /sub h/=11.5 nm for aluminosilicate fibers.<>
