Abstract
Mode-locking (ML) of lasers allows obtaining periodic trains of short optical pulses (ps or shorter) at repetition rates that depend on the cavity length. Mode-locked pulses are employed in a variety of domains such as telecommunications, metrology, remote sensing or material processing. Producing short pulses requires a wide material gain spectrum; thus, lasers that use a Semiconductor Optical Amplifier (SOA) as gain element in a fiber-based cavity have been developed [1-3]. For ring cavities, these have achieved producing 800~fs pulses at the fundamental ML frequency of 14 MHz by passive ML based on nonlinear polarization rotation in the SOA [2]. Also, a figure-of-eight laser (F8L) operating at 1.06 µm has been developed, yielding pulses of 29 ps duration and repetition rates from 30 MHz to 12 GHz [3].
