We demonstrate efficient optical parametric amplification and generation in a gas-filled hollow-core fiber of near-infrared pulses, peaked at 1.4 microm wavelength, with 5 microJ energy and 45 fs duration at the fiber output. Numerical simulations confirm that the OPA is phase matched through excitation of higher-order fiber modes.
我们展示了在充满气体的近红外空心光纤中有效进行光参量放大和产生的过程，近红外脉冲峰值波长为 1.4 微米，在光纤输出端能量为 5 μJ，脉宽为 45 fs。数值模拟证实，通过激发高阶光纤模式实现了光参量放大的相位匹配。
