摘要：
In this paper, we report recent progress in long-period fiber gratings (LPFGs) fabricated by using a new writing technique that is mainly based on the thermal shock effect of focused high-frequency CO2 laser pulses at several kHz. The writing mechanism of this technique is reported for the first time to our knowledge. Novel sensor systems for low-cost measurement of strain and dynamic transverse load are proposed and demonstrated. In addition, phase-shifted LPFGs are fabricated and used for sensing of strain and temperature. Finally, the etching characteristics of these LPFG sensors are investigated.
