Abstract

We report on ultra-short stretched pulse generation in an all-fiber erbium-doped ring laser with a highly-nonlinear germanosilicate fiber inside the resonator with a slightly positive net-cavity group velocity dispersion (GVD). Stable 84 fs pulses were obtained with a 12 MHz repetition rate at a central wavelength of 1560 nm with a 48.1 nm spectral pulse width (full width at half maximum, FWHM) and 30 mW average output power; this corresponds to the 29.7 kW maximum peak power and 2.5 nJ pulse energy obtained immediately from the oscillator.

摘要

我们报道了在一种全光纤掺铒环形激光器中产生超短拉伸脉冲的情况，该激光器的谐振腔内有一根高非线性锗酸盐光纤，净腔群速度色散（GVD）略为正值。在中心波长1560nm处，以12MHz的重复频率获得了稳定的84fs脉冲，光谱脉冲宽度（半高全宽，FWHM）为48.1nm，平均输出功率为30mW；这对应于直接从振荡器获得的29.7kW最大峰值功率和2.5nJ脉冲能量。
