Abstract
A novel micro fiber optic high-temperature pressure sensor based on femtosecond laser processing technology is designed and manufactured. The sensor is a Fabry-Perot cavity which is manufactured on the end of the fiber end-face. The interferometric pressure sensor possesses high sensitivity, high resolution and can work under an extreme high temperature(as high as 1100℃)circumstance. The linear output property is achieved at different temperature. It is a promising sensor to measure the pressure in high temperature applications.
