摘要: 本實驗以波長1550 nm的脈衝雷射(Regular pulse)泵浦一段高非線性光纖(Highly nonlinear fiber, HNLF)。經由前級放大器(Pre-amplifier)與助推器(Booster)放大後的脈衝雷射,其脈衝重複率、平均功率與脈衝寬度分別為19 MHz、5.22 W 與23.1 ps,泵浦高非線性光纖後產生一個功率頻譜密度在20 dBm/nm下帶寬約為1133 nm的超連續光譜,涵蓋範圍從1020至2153 nm且平均輸出功率高達3.34 W。
We report the generation of supercontinuum by well-defined laser pulses at 1550 nm through a piece of 1-meter highly nonlinear fiber. The laser pulses at 19 MHz repetition rate were amplified to an average power of 5.22 W by the pre-amplifier and the booster, and the pulse duration is 23.1 ps. The supercontinuum has an optical spectrum spanning from 1020 to 2153 nm, and its average power is 3.34 W.
