Description
Introducing our advanced Ceramic Reflector, a high-quality focusing cavity material that stands out due to its exceptional diffuse reflection characteristics, robust mechanical properties, and superior chemical structural stability. These ceramic materials are designed to provide a more uniform irradiation light field on the laser working substance, ensuring an even pump across the entire cross-section. This uniformity is crucial for optimizing laser performance and efficiency. Ceramic Reflectors are crafted from alumina ceramic, known for its impressive physical properties. These reflectors boast a fully glazed surface, which not only enhances their reflectivity but also makes them easy to clean. The glazing process ensures that the reflectivity reaches up to 98% at wavelengths of 600-1000 nm, and exceeds 96% in the frequency range of 400-1200 nm. Such high reflectivity is essential for maximizing the effectiveness of lamp-pumped solid-state lasers, which are widely used in various industries including medical, welding, cutting, and marking. The durability of our Ceramic Reflector is unmatched, thanks to its high-strength characteristics and appropriate porosity. It offers a long service life, making it a reliable choice for demanding applications. With a bulk density of 3.1 g/cm³ and a purity level exceeding 99%, this product is engineered to withstand rigorous conditions. Its thermal shock resistance allows it to endure cycles from 15-100°C without cracking, and it features a thermal expansion coefficient suitable for a wide range of temperatures. Our standard Ceramic Reflectors are available in various sizes, all featuring full glazing for optimal performance. Whether you require a specific dimension or need a custom solution, our team is ready to assist you in selecting the right product to meet your needs.
