Single-frequency fiber lasers don’t have to be sensitive to vibration! The "Rock" is a stable single-frequency fiber laser with ultralow phase noise that is insensitive to vibration, without the need of active stabilization.

The Rock is about 100 times less sensitive to vibration than typical fiber lasers and eliminates the need for active stabilization and complex antivibration mounts. The laser can be easily implemented in a variety of OEM laser solutions and is the new building block for NP Photonics' new multilaser systems.

The Rock is based on a passive stabilization technique recently developed by NP Photonics for DWDM (dense wavelength division multiplexing) fiber-optic sensing systems. This method significantly reduces the sensitivity of the frequency noise to vibration and low frequency acoustics.
