In this paper, we report novel 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 CO 2 laser pulses at several kHz. Several unique characteristics of these LPFGs, such as bend and transverse-load,
## Abstract An accelerometer based on the strain and bend characteristics of long period fiber grating (LPFG), which fabricated in common communication optical single mode fiber by using CO~2~ laser pulses, is investigated in this article. The relationship between vibration of the uniform strength
