Abstract

Applications in telecommunication and instrumentation currently drive a vigorous research effort towards the construction of tunable high power sources of picosecond pulses.¹ Particularly, passively-mode-locked fiber lasers appear very attractive for providing these functions; however, a problem has been that passively-mode-locked fiber lasers typically tend to produce pulses near the bandwidth limit of the gain medium, giving rise to pulses significantly shorter than 1 ps.²
