By using the novel approach for pulse compression that combines spectral broadening in hollow-core fiber (HCF) with linear propagation in fused silica (FS), we generate 1.6 cycle 0.24 mJ laser pulses at 1.8 μm wavelength with a repetition rate of 1 kHz. These pulses are obtained with a white light seeded optical parametric amplifier (OPA) and shown to be passively carrier envelope phase (CEP) stable.
通过采用一种新颖的脉冲压缩方法，该方法将空心光纤（HCF）中的光谱展宽与熔融石英（FS）中的线性传播相结合，我们在1.8μm波长、1kHz重复频率下产生了1.6周期、能量为0.24mJ的激光脉冲。这些脉冲是通过白光种子光参量放大器（OPA）获得的，并被证明是被动载波包络相位（CEP）稳定的。
