Environmentally stable high-power erbium fiber soliton lasers are constructed by Kerr or carrier-type mode locking. We obtain high-energy pulses by using relatively short fiber lengths and providing large amounts of negative dispersion with chirped fiber Bragg gratings. The pulse energies and widths generated with both types of soliton laser are found to scale with the square root of the cavity dispersion. Kerr mode locking requires pulses with an approximately three times higher nonlinear phase shift in the cavity than carrier mode locking, which leads to the generation of slightly shorter pulses with as much as seven times higher pulse energies at the mode-locking threshold.
环境稳定的高功率铒光纤孤子激光器通过克尔或载流子型锁模构建。我们通过使用相对较短的光纤长度并利用啁啾光纤布拉格光栅提供大量负色散来获得高能量脉冲。发现两种类型的孤子激光器产生的脉冲能量和宽度与腔色散的平方根成比例。克尔锁模在腔内所需的脉冲非线性相移比载流子锁模大约高三倍，这导致在锁模阈值处产生略短的脉冲，其脉冲能量高达七倍。
