Abstract

A four-layer tri-wavelength silica antireflective (AR) coating with 100% transmittance simultaneously at 1064 nm, 532 nm and 355 nm was designed based on the vector method combined with absentee layer. The type of this AR coating is λ/2-λ/4-λ/2-λ/4 (λ 0 = 532 nm): 1.0|L A1 H A2|1.46 with n L = 1.19, n A1 = 1.31, n H = 1.44 and n A2 = 1.33.
