摘要:
激光器为谐振式光纤陀螺(R-FOG)的关键器件,根据R-FOG对激光器的要求,提出了一种R-FOG用激光器最佳工作点及最优工作区间的确立方法,制定了激光器性能自动化测试方案,得到激光器光功率、中心波长与电流、温度的变化关系。由此推导出2个激光器电流与温度的最佳工作点,并利用拍频检测原理确立2个激光器电流与温度的最优工作区域。激光器最优工作区域的掌握,为其应用于R-FOG提供了详实的参数指标。

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.
Key words:  Resonator fiber optical gyroscope  Semiconductor laser  Best work point  Optimum work area
