PowerLocker™ wavelength stabilization gratings are Volume Bragg Gratings (VBGs) that lock the emission of a laser diode into a narrowed optical spectrum, increasing spectral brightness and ensuring highly stable optical performance over extended temperature ranges.  PowerLocker™ gratings enable compact external cavity designs that deliver superior mode selection and wavelength stability without compromising power output.
 
Engineered with holographically recorded gratings within the volume of glass, PowerLocker devices are robust, long-lasting, and stable under a wide range of operating conditions and optical intensities.  Our patented manufacturing process ensures consistency, reproducibility, and full traceability, with the flexibility to rapidly target new specifications for evolving applications.
