We manufactured FBG by the non-heat process which used femto-second ultra-fast pulsed laser. Processing and a high temperature examination were previously done with the quartz board, and it checked that grating structure was tolerant to 950℃. As a result, we confirmed that the trial production of a heat-resistant FBG sensor was possible, with the combination of ultra-fast pulsed laser and the processing technology in a microscope.

我们采用飞秒超快脉冲激光非加热工艺制备了光纤光栅。之前对石英板进行了加工和高温检查，并检查了光栅结构耐受950℃。因此，我们证实了通过超快脉冲激光和显微镜加工技术的结合，可以试制耐热FBG传感器。
