Reflectors and flow tubes

Laser reflectors consist of monolithic blocks of transparent materials and serve simultaneously as filters, reflectors and heat conductors.
Such reflectors are milled out of a rod or block of a selected material.
The material used is usually undoped or rare earth doped quartz glass with high optical quality.
To create the reflective outer surface, silver coatings are applied using chemical or electrochemical methods.

Materials used:

  •   Quartz glass
  •   Cerium-doped quartz glass
  •   Europium-doped quartz glass
  •   Samarium-doped glass S7005, S7010
  •   Pyrex glass
  •   Borofloat 33
  •   Other materials


Standard dimensions and tolerances:

  •   Inner diameter: 2-40mm (±0.05-0.10mm)
  •   Length: 10-130mm (±0.05-0.10mm)
  •   Parallelism: 0.05-0.1mm


Reflectors can also be made to customer specifications.

The mirrored reflectors for diode-pumped lasers consist of quartz glass or sapphire tubes with silver and a protective coating applied to the outer surface.
Some areas of these reflectors are uncoated and serve as windows for the laser diodes used for pumping.
To ensure that the window size of such reflectors is ideally matched to the dimensions of the pump source, these reflectors are manufactured to customer specifications.
