Excellent work. With some headscratching, we may soon be able to figure out how to couple cheapo 500W laser diode stacks to fibers for building laser cutters for metal. 500W laser Diodes are available for around $1000 like https://www.alibaba.com/product-detail/ ... 61539dmDmO. And this guy talks about how to simulate the raytracing - https://www.aphys.kth.se/polopoly_fs/1. ... s_2009.pdf . It is great that FreeCAD can be extended to just about anything.

Bonus points for hooking this up with FEM and melting something with focused light ;). -Ian-
This sounds awesome.. can this seriously be done?
I recently found out, there is a program called "Comsol". It cost some serious $$$$$, but apparently it can do pretty much anything physics-related, mechanics, cfd, electrodynamics, acoustics, plasma physics, semiconductors, ..., and custom equations. And allows to tie all these disciplines into one problem. I'm slowly looking into attending a course, it looks like it can elevate engineering caps to a whole new level.

Yep.
1x basic module + 40 addons ==> 34000 USD
In germany, a nurse must work 2 years for that... ;)

The linked pricelist is the Educational Discount Plan. I wonder what FreeCAD charges from universities :mrgreen: .

Just a few videos from an commercial optical design package... Putting everything together what has been shown and discussed in this topic does show some good potential
