I'm very confused by the description of the laser cavity. Why would the porro prism change the polarization of the beam? Is the laser cavity formed by two beams in the paper plane the upper one propagating towards the Q-switch and the lower one towards the gain medium? Maybe the polarizer only covers the upper part of the beam.
I am not an expert in optics, it is written like this on the small description in the book literally « Porro prism reflects energy and rotates plane by 90º »
Very interesting, thanks
Great videos.
awesome

Merci, meilleurs vœux à vous aussi et à tous ceux qui liront cette réponse. Je suis à une dizaine dekm de Roissy CDG
What is the pulse repetition frequency? I guess it must be quite high (>30Hz) for the quadrant detector to be able to follow a target.
According to the book it is between 10 and 20 Hz
