A laminated, optical filter lens (10) having particular application in a high-fluence laser, and a method of forming such lens. The filter lens (10) comprises a core (12) and a cladding (14 and 16), the core (12) having an essentially pure, single, fused oxide composition and the cladding (14 and 16) having a fused oxide composition different from that of the core (12) and having a coefficient of thermal expansion lower than that of the core (12). |
