Accuflect® Ceramic Laser Reflectors Accuflect® ceramic laser reflectors are engineered to deliver high efficiency and nearly perfect diffuse reflection. These reflectors are specifically designed to enhance performance in laser systems, particularly those with laser hosts operating within the 500 nm to 1200 nm spectral range. The unique properties of Accuflect® reflectors make them an integral component for optimizing light management in various laser applications.

There are two distinct grades of Accuflect® ceramic available for laser reflectors: Accuflect® B6 and Accuflect® G6. Accuflect® B6 features a native ceramic surface, characterized by approximately 30% porosity, which ensures nearly perfect lambertian reflectance with minimal absorption losses. This makes it ideal for dry cavity laser applications, such as low energy air-cooled systems or high-energy systems where the reflector is isolated from liquid coolants using o-ring sealed flow tubes. Accuflect® G6, on the other hand, boasts a glazed surface that is impervious to coolants and their potential contaminants. This makes it particularly suitable for compact, high-energy flooded cavity laser heads.

The glazed surface provides approximately 4% specular reflectance when measured at an 8° angle from normal, which is significantly reduced in flooded cavities due to the refractive index match between the coolant and the glazed surface. Accuflect® laser reflectors offer numerous advantages over traditional PTFE polymer reflectors, polished metal specular reflectors, and packed powder diffuse reflectors. These include highly efficient reflection that reduces the need for precision focusing reflectors, a uniform light field that ensures a consistent output beam profile, and the elimination of hot spots, which can reduce Amplified Spontaneous Emission (ASE). Additionally, the robust ceramic material is resistant to breakage, corrosion, and damage from surface contaminants, ensuring durability and reliability in demanding environments.
