A fiber ring laser that can produce nearly transform-limited soliton pulses is simulated. This laser has an erbium-doped optical-fiber amplifier and allows wavelength tuning through the interplay of fiber chromatic dispersion and the round-trip delay time of the laser. We show that a saturable absorber and a frequency limiter are required for the ring laser to self-start, i.e., to mode lock from initial noise and to operate stably. We also show that nonlinear polarization rotation with polarization selectivity inside the ring can act as a saturable absorber.
对一种能够产生近变换极限孤子脉冲的光纤环形激光器进行了模拟。该激光器具有掺铒光纤放大器，并通过光纤色散与激光器往返延迟时间的相互作用实现波长调谐。我们表明，环形激光器要实现自启动，即从初始噪声中锁模并稳定运行，需要一个可饱和吸收体和一个频率限制器。我们还表明，环形腔内具有偏振选择性的非线性偏振旋转可充当可饱和吸收体。
