利用激光二极管泵浦的非线性放大环镜掺铒光纤激光器，首次获得了290 fs的1.56 μm孤子脉冲。激光器由InGaAsP激光二极管泵浦，并且开始脉冲振荡的阈值为50 mW。被动锁模持续到低至10 mW的泵浦功率水平。重复率是不可控的，并且在5 MHz和1.2-2 GHz的基本重复率之间变化。
290 fs soliton pulses at 1.56 μm have been successfully obtained for the first time from a laser‐diode pumped erbium‐doped fiber laser with a nonlinear amplifying loop mirror. The laser was pumped by InGaAsP laser diodes and the threshold for starting the pulse oscillation was 50 mW. The passive mode‐locking continued to a pump power level as low as 10 mW. The repetition rate was uncontrollable and varied between the fundamental repetition rate of 5 MHz and 1.2–2 GHz.
