Laser Reflectors

Morgan Technical Ceramics ceramic laser reflectors are high reflectance cavities used in solid state and CO₂ laser systems. They are designed either as a one-piece or two-piece system, depending on customer requirement.

Benefits of our Custom Range of Ceramic Laser Reflectors

• Significant advantages and improvements over those made with materials such as metal and polymer
• Extended life time
• Higher efficiency/output performance
• Higher reflectance over a wider range of wavelengths - Sintox™ AL shows reflectance of 97 to 98% over wavelengths from 570nm to 2000nm. Sintox™ FF shows reflectance of 96 to 98% over wavelengths from 570nm to 2000nm
• Inert to all common cleaning chemicals
• Uniform beam quality
• Greater thermal stability, particularly at higher temperatures due to a very low coefficient of thermal expansion
  
  

High reflectance Sintox™ AL and Sintox™ FF ceramic cavities generate diffuse reflectance, which provides a highly uniform beam profile. This diffuse reflectance also scatters light and consequently reduces hot spots in the pumped medium. These fully dense materials show higher strength and scratch resistance than traditional polymeric and thermoplastic materials. Furthermore, the mechanical strength of the material allows the design and manufacturing of thin wall section reflectors to minimise the laser’s final assembly weight and design space requirements. 

When active cooling is required, the reflectors can be glazed both inside the cavity and around the outer edges using 'non-solarising' glaze that seals the ceramic against ingress of cooling fluids. 

Types of Glazed Laser Reflectors Available

1. Sintox™ AL GSO: solarisation resistant glaze providing high bulk reflectivity.
2. Sintox™ AL GSY: this glaze cuts off wavelengths in the UV range which reduces the amount of heat generated in the laser head with the benefit of extended service life, reduced cooling requirements and in some cases reduces operating costs.
3. Sintox™ AL Samarium: absorbs radiation at the Nd-YAG lasing wavelength of 1,064nm, and its further transitions near 940nm, 1120nm, 1320nm and 1440nm. Absorbing this radiation prevents it from being reflected back into the laser rod and increases maximum output energy.
