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. More information about the gratings can be found in the Technology section of our website, under Publications.
The PowerLocker® is patent protected by U.S patent 5,691,989.
Inventory of volume holographic gratings available on the online store. Custom wavelengths and efficiencies available in 4-6 weeks. Call 626.357.9600 or e-mail requests at sales@ondax.com.
