ABSTRACT
We develop an all polarization-maintaining (PM) 920â
nm Nd-doped fiber amplifier delivering a train of pulses with â¼0.53â
W average power and sub-50â
fs duration. The sub-50â
fs pulse benefits from the pre-chirping management method that allows for over 60â
nm broadening spectrum without pulse breaking in the amplification stage. By virtue of the short pulse duration, the pulse peak power can reach to â¼0.31â
MW in spite of the moderate average power. These results represent a key step in developing high-peak-power pulse Nd-doped fiber laser systems at 920â
nm, which will find important applications in fields such as biomedical imaging, ultrafast optical spectroscopy, and excitation of quantum-dot single photon sources.
