摘要：

The effects of pulse power, filling ratio, number of period and period on the long-period fiber gratings (LPFGs) by using radiation of femtosecond laser. The results show that the strong resonance peaks of LPFGs can be induced and the resonant peaks have different degrees of offset. When the parameters of the LPFG are set to be number of grating period of 70, filling ratio of 0.5, pulse power of 2.0 mW and period of 500 mu m, the first resonance peak of LPFG has a blue-shift of 147.3 nm. Furthermore, the size of first resonance peak of LPFG is -19.4 dB. These characteristics of LPFGs provide a favorable opportunity for in-depth research of late-model sensing devices.
