- Abstract summary: 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.

- Abstract: 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.

Solid state defects in diamond make promising quantum sensors with high sensitivity andtemporal resolution.
Inhomogeneous broadening and drive amplitude variations have differing impacts on the sensitivity depending on the sensing scheme used.
We numerically investigate and compare the predicted sensitivity of schemes based on continuous-wave (CW) optically detected magnetic resonance (ODMR) spectroscopy, pi-pulse ODMR and Ramsey interferometry.

The device consists in a plasmonic nanocavity hosting a small number of molecules. The incoming field resonantly drives a collective molecular vibration, which imprints an optomechanical modulation on a visible pump laser.

We introduce a technique of continuous vybroadband back action avoiding measurements.
The method involves a dichromatic optical probe resonant with the MSI modes.
We show that analyzing each of the harmonics of the probe reflected from the mechanical system separately and postprocessing the measurement results allows excluding the back action in a broad frequency band.
