Gratings and Filters
Volume Bragg Gratings (VBGs) from Ondax are solid-state holographic filters formed within proprietary photosensitive glass. They provide ultra-stable, degradation-free performance across a wide range of conditions and optical intensities. Through patented manufacturing and rigorous testing, Ondax ensures exceptional consistency, reproducibility, and full traceability in every VBG.
PowerLocker™ Wavelength Stabilization Gratings
These 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 in a compact external cavity design without compromising power output.

NoiseBlock™ ASE Filters
These filters suppress ASE by >70 dB while transmitting up to 90% of the laser line. Available in both classic diffractive and compact transmissive designs, they are ideal for applications requiring rejection of ASE very close to the laser. Perfectly matched to SureBlock filters for ultra-low-frequency Raman
