We operate a frequency-stable laser in a non-laboratory environment where the test platform is a passenger vehicle. We measure the acceleration experienced by the laser and actively correct for it to achieve a system acceleration sensitivity of Δf / f = 11(2) × 10(−12)/g, 6(2) × 10(−12)/g, and 4(1) × 10(−12)/g for accelerations in three orthogonal directions at 1 Hz. The acceleration spectrum and laser performance are evaluated with the vehicle both stationary and moving. The laser linewidth in the stationary vehicle with engine idling is 1.7(1) Hz.
我们在非实验室环境中操作一台频率稳定的激光器，测试平台为一辆乘用车。我们测量激光器所经历的加速度，并进行主动校正，以实现系统在1 Hz时三个正交方向加速度下的加速度灵敏度分别为Δf / f = 11(2)×10(−12)/g、6(2)×10(−12)/g和4(1)×10(−12)/g。在车辆静止和行驶状态下评估加速度谱和激光性能。发动机空转时静止车辆中的激光线宽为1.7(1)Hz。
