We report on the generation of 9.0 fs, 550 μJ, carrier-envelope phase (CEP)-stabilized optical pulses around 1.6 μm at 1 kHz. Few-cycle IR pulses are obtained from a BiB(3)O(6) optical parametric chirped-pulse amplifier. The amplification of nearly octave-spanning ultrabroad pulses without spectral broadening results in good stability in output energy (0.85% rms) and CEP (160 mrad rms). We observed high harmonics in the water window from a neon cell that corresponds to a laser intensity of 4.1×10(14) W/cm(2).
我们报告了在 1 kHz 下产生 9.0 fs、550 μJ、载波包络相位 (CEP) 稳定的 1.6 μm 附近光脉冲的情况。几周期的 IR 脉冲是从 BiB(3)O(6)光参量啁啾脉冲放大器获得的。近倍频程超宽带脉冲的放大而没有光谱展宽导致输出能量（0.85% rms）和 CEP（160 mrad rms）的稳定性良好。我们从氖气室中观察到了对应于 4.1×10(14) W/cm(2)的激光强度的水窗中的高次谐波。
