Reflectors and Flowtubes

Laser reflectors consist of monolithic blocks of transparent material and serve as filter, reflector, and heat conductor at once. Such reflectors are milled from a rod or block of a selected material. The material used is usually undoped or with rare-earth doped quartz with a high optical quality. To create a reflective outer surface, silver coatings are applied using chemical or electrochemical methods.

Used materials:

  •   fused quartz
  •   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 be also manufactured according to the customers' requests.


Mirrored reflectors for diode-pumped lasers consist of quartz glass or sapphire tubes, on whose outer surface silver and a protective coating are applied. Some areas of these reflectors are uncoated and serve as windows for pumping by the laser diodes. To ensure that the window size of such reflectors is ideally adapted to the dimension of the pump source, they are manufactured according to the customer’s wishes.
