We extend the concept of broadband phase matching in a noncollinear optical parametric amplifier (NOPA) to the near-IR. In an 800 nm pumped NOPA using periodically poled stoichiometric lithium tantalate, we amplify a spectrum spanning the 1.1-1.7 microm range and corresponding to two optical cycles of the carrier wavelength. A limited portion of the spectrum is compressed by a prism pair down to 16 fs.
我们将非共线光学参量放大器（NOPA）中的宽带相位匹配概念扩展到近红外波段。在一个使用周期性极化化学计量比钽酸锂的800纳米泵浦NOPA中，我们放大了一个跨度为1.1 - 1.7微米范围且对应于载波波长两个光学周期的光谱。该光谱的有限部分通过一对棱镜被压缩至16飞秒。
