✦ Synopsis

A passively mode-locked fiber ring laser is demonstrated using a 49 cm long bismuth oxide based erbium-doped fiber (Bi-EDF) and a fast semiconductor saturable absorber. Stable and clean short pulses are achieved because of these short and high nonlinear characteristics of the Bi-EDF. The laser operates at 1560 nm with a repetition rate of 8.3 MHz and a center wavelength of 1560 nm. The calibrated auto-correlator pulse trace of the laser shows a sech 2 pulse shape, with an estimated pulse width of 340 fs.

Supercontinuum generation with considerable flatness and low fluctuation is investigated in nonlinear fibers by amplification of pulsed seed signal of a stable mode locked bismuth oxide based erbium doped fiber laser. Spectral expansion from 980 to 1750 nm is obtained by 340 fs pulses at 1560 nm amp
