Adjustable narrow band holographic reflective filter with the absolute diffraction efficiency about 95% has been recorded in the volume of photo-thermo-refractive glass. Attenuation up to 20 times of transmitted beam was observed. Advantages of holographic filters in inorganic glass for laser power attenuation are discussed.
