circular polarizers for cameras

[sddfds]

hello i would like to ask if i use a laser pointer and a camera circular polarizer will a circularly polarized waves be generated. thanks very much.

What's a "vortex"?

Yes, but efficiency may suffer because it was made to work for white light and you're using it with monochromatic light. Another name for a circular polarizer is a quarter-wave retardation plate.

pass the laser through a regular polarizer to isolate one polarization then pass this through a 1/4 wave plate at 45 degrees to the laser. This should result in circular polarized light.

google is your friend. https://en.wikipedia.org/wiki/Circu...f producing circular polarization in practice.
