Ondax's PowerLocker^® is ideal for increasing the brightness of high power laser diodes and locking their emission wavelength. The short external cavity enabled by the PowerLocker^® provides better mode selection than systems based on Littrow and Littman cavities.

The PowerLocker^® is a volume holographic glass grating which reflects a specified wavelength at a given reflectivity. Results from PowerLocker^® stabilization with single emitters, bars and stack of bars are discussed in the Photonics Spectra article.

The PowerLocker^® is patent protected by U.S patent 5,691,989.

Inventory of standard volume holographic gratings available. Custom wavelengths and efficiencies available in 4-6 weeks.
