Standing ovation! I'm speechless! What a very cool concept!
If a mount(s) could be designed to fine tune the mirror angles and insertion into the beam then this would be an awesome way to tame these crazy diodes.
In theory you could do this a couple of times on the same beam. What is so elegant about this solution is the flatter the beam, the more you could use its width to thicken up the height of the output beam.
Very impressed
