Ray Tracing Simulator: Simulating Gaussian Beam in Bow Tie Cavity

Click For Summary
SUMMARY

The discussion centers on the use of ray tracing simulators for modeling Gaussian beams in bow tie cavities. Winlens Basic from Qioptiq is recommended as a suitable free tool for this purpose. Users may need to manually incorporate astigmatism effects due to tilted mirrors, but with knowledge of the focal length shift, effective ray tracing can be achieved. This information provides a practical solution for those looking to simulate optical behaviors in specific cavity designs.

PREREQUISITES
  • Understanding of Gaussian beam properties
  • Familiarity with ray tracing concepts
  • Basic knowledge of optical cavity design
  • Experience with Winlens Basic software
NEXT STEPS
  • Research the implementation of astigmatism in ray tracing simulations
  • Explore advanced features of Winlens Basic for optical simulations
  • Learn about the effects of focal length shifts in optical systems
  • Investigate other ray tracing software options for optical cavity simulations
USEFUL FOR

Optical engineers, physicists, and researchers interested in simulating Gaussian beams and designing optical cavities will benefit from this discussion.

Hello! Is there any good free ray tracing simulator? I just want to simulate the behavior of a Gaussian beam in a simple bow tie cavity. Thank you!

I don't believe there is any simulation platform that was made with cavities in mind. If you want a good free ray tracing simulator, try Winlens Basic from Qioptiq. I think you will need to hard-code the astigmatism from the tilted mirrors into the simulation, but if you know the focal length shift then the ray tracing should work just fine. Hope that helps!
