  • The 'Rock' Fiber Laser
Apr 2007
NP Photonics Inc.Request Info
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.

fiber laser
A laser in which the lasing medium is an optical fiber doped with low levels of rare-earth halides to make it capable of amplifying light. Output is tunable over a broad range and can be broadband. Laser diodes can be used for pumping because of the fiber laser's low threshold power, eliminating the need for cooling.
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
