Abstract
At present, search and creation of means for protecting photodetective devices and visual human organs against high power laser radiation is one of vital tasks for researchers designing opto-electronic devices and systems of various purposes. FGUP "NPO GIPO" possesses narrowband hologram filters (Notch filters) production technology which enables to design unique optical filters and to product in serial quantity the standard ones with high technical characteristics. These filters exhibit high beam damage threshold and make available the effective suppression of laser radiation (up to 7 orders) with high transmittance value outside the notch (up to 90%); they may have either one or simultaneously several nothces in a region of 0.4-1.5 μm. Notch-filters can be made both on plane surfaces and on the convex and concave ones with diameters up to 80 mm. The report presents layouts for recording and certifying filters as well as technical characteristics of some filters at different wavelengths.
