Laser Ceramics Questions
Why are ceramics used as laser materials?
Ceramics are specified because of ceramics’ high reflectance at critical wavelengths, e.g. 98%+ reflectance at 1064nm, coupled with exceptional and uniform thermal stability, low electrical loss, resistance to solarisation and oxidation, corrosion resistance to gases and fluids (such as fluorine compounds, CO2, cooling fluids and cleaning fluids), cleanliness, and hardness. The high reflectance is obtained by a combination of the material properties, microstructure and controlled porosity of the material.
What are the advantages of ceramic laser components over other materials?
While other materials (such as polymers, polished aluminium, and gold or silver-plated fused silica or glass) can demonstrate the required reflectance at a desired wavelength, they often lack sufficient additional attributes which detrimentally impacts long-term laser quality (e.g. thermal stability, corrosion resistance, cleanliness, durability during maintenance). Furthermore, the reflectors made out of alumina ceramic, e.g. Sintox™ AL, have high reflectance over a wide range of wavelengths, e.g. 98% reflectance across the wavelength range 500 – 2000nm.
How are ceramics used in laser components?
Ceramics components reflect light to concentrate the light energy to amplify an intense, coherent, collimated beam of light at a specific nominal wavelength, a “laser beam.” Because of the high-energy needs of some of these systems, ceramics are often used as electrical feedthroughs for their high electrical resistivities.
