We generate self-carrier-to-envelope phase-stable, 630 μJ pulses, centered at 2.1 μm, with 42 fs (6 cycle) duration based on collinear optical parametric amplification in BiB(3)O(6) at 3 kHz. These pulses are generated through a traveling wave amplifier scheme, and the bandwidth supports 28 fs (4 cycle) pulse duration. Carrier-to-envelope phase stability was measured to be 410 mrad over 10 min or 260 mrad over 35 s.
我们在 BiB(3)O(6)中基于共线光参量放大产生了中心波长为 2.1μm、自载波到包络相位稳定、630μJ 的 42fs（6 个周期）脉冲，重复频率为 3kHz。这些脉冲是通过行波放大方案产生的，带宽支持 28fs（4 个周期）的脉冲持续时间。经过 10 分钟或 35 秒的测量，载波到包络相位稳定度分别达到 410mrad 和 260mrad。
