Summary: | A passive harmonically mode-locked fiber laser cladding pumped by a broad-area diode-laser array is described. Harmonic mode locking is obtained in a frequency range from 33.3 to 128.6 MHz, where the higher frequency limit is imposed because of insufficient available pump power. The maximum pulse jitter in one cavity round-trip time is between 300 and 50ps in the whole frequency range, and the sidebands in the frequency domain are suppressed by as much as 50dB. 600-fs bandwidth-limited pulses with pulse energies of as much as 20pJ are obtained, giving rise to an average output power as great as 2.5mW |
