PROJECT TITLE :

Self-Started Mode-Locking With Dispersion-Imbalanced Nonlinear Amplifier Loop

ABSTRACT:

Self-started mode-locking in an exceedingly polarization-maintaining figure-eight Er-doped fiber laser was demonstrated by optimizing the dispersion and also the nonlinearity in the nonlinear amplifier loop mirror. Experimental results indicate that the build-up time of soliton pulse is directly linked to the on the market pump power and internet dispersion. 3 laser diodes, one in a very linear loop and therefore the others in an exceedingly nonlinear loop, were applied to provide enough pump power for the beginning-up of the nonlinear evolution. As long as eight-min build-up time was observed as the web dispersion approaches to −zero.115 and −zero.043 ps2, it dramatically decreased to approximately millisecond order of magnitude as the web dispersion was optimized to −0.062 ps2. Stable single soliton could be obtained by reducing the hysteresis pump power.
