The pressure sensor structure utilizes a linear cavity erbium-doped fiber laser which is formed by a fiber Bragg grating (FBG) at one end of laser cavity. The FBG acts simultaneously as a wavelength reflector and pressure sensor to measure static pressure applied by a shock tube facility. The sensor is tested to measure a static pressure from 0 to 10 bar. The fiber laser pressure sensor has characteristics of simple configuration, high output power of 3.571dBm, stable output wavelength and power and high signal-to-noise ratio over 55 dB .This sensor is expected to be an attractive choice for long-distance pressure monitoring
