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
