High power laser applications require special designed optical parts and systems like F-Theta-Ronar lenses or Faraday Isolators to ensure the required performance and precision during welding, drilling or additive manufacturing processes as well as laser protection. Objectives or Faraday Isolators which are not optimized for high laser power applications cannot maintain good beam quality at high laser power densities. Thermal lensing, depolarization and photo-contamination effects must be taken into account in the designs and manufacturing of optical parts and sub-modules used for high power lasers and applications. We report on our concepts to find a balanced trade-off between performance requirements for the optical parts and maintaining of the required high end beam quality to ensure best results during application.

 

 

 

PLANNED CONTENT and STRCUTURE:

 

  • Introduction
  • Beam degradation effects of optics used at high power laser densities
  • What is thermal lensing?
  • Transmittance of glass or quartz materials and its limitations!
  • What is depolarization and photo-contamination?
  • The role and interaction of FEM and optical design to find a solution
  • Keep the materials under control
  • Glass/quartz material selection and control
  • New coatings are necessary
  • New low absorption material (KTF)
  • Get rid of outgassing auxiliary materials
  • Measurement, monitoring and qualification
  • Application examples and results
  • Low absorption F-Theta-Ronar lens
  • Beam Expander for high laser power
  • Medium and High Power Faraday Isolators
  • Low outgassing Faraday Isolator
