Investigation of a Large Mode Area Pulsed 1550 nm Laser System

Not Accessible

Your library or personal account may give you access


An Ultra Large Mode Area (ULMA) erbium doped optical fiber having a 52 micron core was investigated as the high power stage of a 1550 nm pulsed fiber laser system. The ULMA fiber was seeded with 1550 nm light from a 4 stage all fiber pulsed laser system with pulse energies of 11.35 and 6.25 μJ at pulse widths of 300 ns and repetition rates of 2 and 10 kHz, respectively. The ULMA fiber stage was counterpumped continuous wave in-band with a 1480 nm Raman laser. Maximum pulse energies (and amplifications) of 360 (15 dB) and 130 μJ (13.2 dB) at 2 and 10 kHz, respectively, were found when pumped with approximately 50 W of 1480 nm pump.
