We report the generation of tunable femtosecond pulses in the near-IR using a two-stage, white-light seeded, collinear, femtosecond optical parametric amplifier (OPA). The OPA, based on BiB(3)O(6) crystal in both stages and pumped at 800 nm by a 1 kHz Ti:sapphire laser amplifier, provides sub-30 fs signal pulses across the whole tuning range of 1.15-1.6 microm with minimum duration of 22 fs and maximum signal energy of 80 microJ.
我们报告了使用两级、白光种子、共线、飞秒光参量放大器（OPA）在近红外产生可调谐飞秒脉冲的情况。该 OPA 在两个阶段均基于 BiB(3)O(6)晶体，并用 1 kHz Ti:sapphire 激光放大器在 800nm 处泵浦，在整个 1.15-1.6 微米的调谐范围内提供小于 30fs 的信号脉冲，最短持续时间为 22fs，最大信号能量为 80μJ。
