In real world real lenses (and also optical systems) increase M^2 parameter of the laser beam.
We know how beam expander affect on Gaussian TEM00 (single mode or M^2=1) beam. We want to predict how same beam expander will work with multimode (high M^2) laser beam.
We work on optical simulation where we use not ideal beam expander.
Not ideal means that for beam expander designed for single mode (M^2=1), the output beam has M^2 >1 (M^2 = M squared)
In our system we want to use beam expander with multimode laser beam.
The beam expander is not ideal (for...
Hello,
I have a 3D complex wave function and I want to apply a unitary transformation to rotate it with respect to arbitrary axis.
Anybody have any ideas how I can do that?

Hello,
Given a 3D gaussian beam incident on a lens at an angle relative to the optic axis, with phase and amplitude on the incident surface known, what is the simplest way to find the phase and the amplitude after propagation through the lens?

I constructing 3D shape of about 2 millimeters sized.
Which kind of optical coating will give me 10 degrees of half view angle for reflected light in visual spectrum ?
thanks
