Narrow-band holographic spectral selector for satellite laser ranging: more stability, new spectral range

摘要

Serial production cycle of narrowband holographic selectors operating at SHG of YAG:Nd~(+3 ) (532 nm) was discussed before. New projects of the satellite laser ranging at 1064 nm require extension of the selector range to the near infrared. Hologram registration technology based on the application of UV He-Cd laser radiation in the photorefractive glass material is presented in the report. New selector operating at 1064 nm having 2 Angstroms spectral selectivity and about 80% diffraction effi-ciency was obtained and tested.
