Laser Reflectors

MACOR® Machining China’ 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.

Our range of custom ceramic laser reflectors offer significant advantages and improvements over those made with materials such as metal and polymer including:

  • 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.

Three types of glazed laser reflectors are available:

a) Sintox AL GSO: solarisation resistant glaze providing high bulk reflectivity.

b) 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.

c) 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.

Our ceramic laser reflectors can be found in a wide range of applications including:

  • Industrial lasers for use with cutting, welding and marking
  • Medical lasers used in ophthalmic and surgical applications
  • Intense Pulse Lamp (IPL) systems for use with hair and tattoo removal
  • DPSS lasers for use in scientific and medical applications plus range finders

A wide range of standard and custom designed laser reflectors with different glaze combinations are available. Some of our standard products we offer are viewable by clicking the links to the right.
