MOPA apparatus (10) includes a mode-locked fiber laser (12) delivering seed-pulses to a regenerative amplifier (26). The seed-pulses are transported via one of two lengths of optical fiber (18,20). One of the lengths of fiber (20) is significantly longer than the other (18), and significantly increases the duration of the seed-pulses. Amplified seed-pulses are compressed in a pulse-compressor (30). The pulse compressor (30) delivers pulses having a pulse-duration of either a few picoseconds, or less than one picosecond, depending on whether the seed pulses are transported respectively by the longer or shorter of the lengths of optical fiber (18,20). |
