Abstract

In view of the special requirements of the high power laser spectral bands and the incident angle, plate dual wavelength laser high reflecting membrane on the K9 optical glass by using electron beam evaporation deposition. Under the condition of vertical incidence, the reflectivity of 532 nm wavelength is higher than 90%; Under the condition of plus or minus 45 ° incident angle, the reflectivity of 1064 nm wavelength at near infrared band is higher than 99.9%. Through material selection, optimization of process parameters and the method of the ion source assisted deposition to improve the membrane layer density and membrane base binding strength, laser-damaged threshold and meet the requirements of the use of optical instruments under certain environmental conditions.
