论文摘要
我们通过将垂直 - 外部腔表面发射激光与单片融合二氧化硅谐振器相结合，从而开发了一种惯性敏感的光力激光器。通过将VECSEL的外部空腔镜放在光学谐振器测试质量上，我们创建了一个传感器，将外部加速度直接转录到激光频率上。我们开发了原则实验室原型，并通过VECSEL激光频率（4.18 +/- .03 Hz）观察传感器的共振频率测试质量振荡。此外，我们设置了一个辅助杂项干涉仪，以跟踪机械振荡器的测试质量的运动，观察到4.194 +/- 0.004 Hz的共振。干涉仪测量值验证了VECSEL结果，证实了使用光力激光器进行惯性感应的可行性。
We have developed an inertially sensitive optomechanical laser by combining a Vertical-External-Cavity Surface-Emitting Laser with a monolithic fused silica resonator. By placing the external cavity mirror of the VECSEL onto the optomechanical resonator test mass, we create a sensor where external accelerations are directly transcribed onto the lasing frequency. We developed a proof-of-principle laboratory prototype and observe test mass oscillations at the resonance frequency of the sensor through the VECSEL lasing frequency, 4.18 +/- .03 Hz. In addition, we set up an ancillary heterodyne interferometer to track the motion of the mechanical oscillator's test mass, observing a resonance of 4.194 +/- 0.004 Hz. The interferometer measurements validate the VECSEL results, confirming the feasibility of using optomechanical lasers for inertial sensing.
