ABSTRACT:
An antireflective coating and a process for producing the same are described. This antireflective coating has the difference in refractive index between the glass interface and the outer surface of the antireflected coating of 0.15 or less. This antireflective coating can be formed by treating a glass with an aqueous solution containing specified amounts of an acidic salt, Al.sup.3+ and Si.sup.4+. The antireflective coating has a high mechanical strength and optical elements having such an antireflective coating are useful for use in the laser nuclear fusion system.
