Abstract

We report on the efficient delivery of sub-picosecond laser pulses with high peak and high average powers through a home-made 7.5 m long tubular inhibited-coupling guiding hollow-core photonic-crystal fiber (IC-HCPCF). The experiments were performed using an ultrafast laser generating pulses with durations between 430 fs and 560 fs at a central wavelength of 1030 nm. Pulses with an energy of either 263 µJ or 150 µJ were coupled into the fiber at average powers of either 48 W or 95 W, respectively. In both cases, the transmittance through the fiber was measured to exceed 85% without detectable distortion of the temporal pulse shapes or damage to the fiber.

通过空心芯光纤高效传输亚ps级激光脉冲，脉冲能量超过100µJ，平均功率高达95 W

本文报道了通过自制的7.5 m长管状抑制耦合引导空心光子晶体光纤（IC-HCPCF）高效传输具有峰值和高平均功率的亚皮秒激光脉冲。实验采用超快激光器，在中心波长1030nm处产生持续时间为430 ~ 560fs的脉冲。能量为263µJ或150µJ的脉冲分别以48 W或95 W的平均功率耦合到光纤中。在这两种情况下，通过光纤的透射率都超过了85%，而没有检测到时间脉冲形状的畸变或对光纤的损坏。
