Laser threshold magnetometry

Caption

Strong coupling between the red-emitting NV centers in the diamond (center) and the cavity field generated by the semiconductor laser (left) allows changes in the magnetic field to switch off the NV-diamond laser system. This produces 100 percent optical contrast together with strong laser readout signals.
