We have developed an inertially sensitive optomechanical laser by combining a vertical-external-cavity surface-emitting laser (VECSEL) 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, $4.18 \pm 0.03\;{\rm Hz}$. In addition, we set up an ancillary heterodyne interferometer to track the motion of the mechanical oscillator’s test mass, observing a resonance of $4.194 \pm 0.004\;{\rm Hz}$. The interferometer measurements validate the VECSEL results, confirming the feasibility of using optomechanical lasers for inertial sensing.

用于惯性传感的光机械激光器。

通过将垂直外部腔表面发射激光器（VECSEL）与整体熔融石英谐振器相结合，我们开发了一种惯性灵敏的光机械激光器。通过将VECSEL的外腔镜放置在光机械谐振器测试质量上，我们创建了一个传感器，其中外部加速度直接转换为激光频率。我们开发了原理验证的实验室原型，并通过VECSEL激光频率$ 4.18 \ pm 0.03 \; {\ rm Hz} $观察了传感器共振频率下的测试质量振荡。此外，我们建立了一个辅助外差干涉仪来跟踪机械振荡器测试质量的运动，观察到的共振为$ 4.194 \ pm 0.004 \; {\ rm Hz} $。干涉仪的测量结果验证了VECSEL的结果，证实了使用光机械激光器进行惯性传感的可行性。
