报道了在镓镧硫化物（GLS）玻璃基片上进行体相位光栅的超快激光刻写（ULI）。研究了激光脉冲能量和光栅厚度对光栅色散特性的影响，旨在提高光栅在中红外波段的性能。具有最佳中红外性能的光栅在1300 nm和2640 nm处的一阶绝对衍射效率分别为61%和24%。基于这里报道的工作，我们得出结论，ULI是有前途的制作中红外体相位光栅，具有潜在的应用，包括天文仪器和遥感。
We report on the ultrafast laser inscription (ULI) of volume phase gratings inside gallium lanthanum sulphide (GLS) chalcogenide glass substrates. The effect of laser pulse energy and grating thickness on the dispersive properties of the gratings is investigated, with the aim of improving the performance of the gratings in the mid-infrared. The grating with the optimum performance in the mid-infrared exhibited a 1st order absolute diffraction efficiency of 61% at 1300 nm and 24% at 2640 nm. Based on the work reported here, we conclude that ULI is promising for the fabrication of mid-infrared volume phase gratings, with potential applications including astronomical instrumentation and remote sensing.
