PowerLocker® wavelength stabilization gratings are designed to reflect a specified wavelength at a given reflectivity, locking the emission wavelength, increasing spectral brightness, and improving environmental performance of laser diodes. The short external cavity enabled by the PowerLocker® provides better mode selection than systems based on Littrow or Littman cavities at a much lower cost. Available in wavelengths from 375nm to 2.5μm, efficiencies from 5% to >99%, and bandwidths from 0.03 to 1nm to match any application requirement.
