Abstract:

Laser source is one of the key components in resonator fiber optical gyroscope (R-FOG). According to the R-FOG requirements to the laser, a method to establish laser optimum working point and optimum working area of R-FOG was proposed. A laser performance test program was developed, through which the relationship between the light power, center wavelength, current and temperature were obtained. On this condition, the optimum current and temperature working points of two lasers were presented, and the beat detection principle was used to establish optimum current and temperature work area of two lasers. To master laser optimum work area provides detailed parameter index for which applied in R-FOG.
