having in my mind the operating principle of crt monitor i thought we could do the same but instead of electrons we could use laser light. having two mirrors one for vertical scanning and one for horizontal which would be oscillated with standard frequency the would project a bright rectangle in the wall. with a good blancking we could project real images instead of vectors and animated pictures.
what horizontal and vertical scanning frequencies do you use?
I am thinkin about the same project but for a RGB laser projector.
Can you define the probles that you have in your setup?

What horizontal and vertical scanning? There's no such thing here... And the problems question is kinda not specifis so it's hard to answer.

very nice. looks like the blanking delay isn't long enough

There's no blanking at all in this setup.

Yea, but it's pulsed... And also how do you define 'brightness' if you can compare a laser to the sun? :|
My most powerful laser is a 808nm 1W diode that is mounted inside the green laser from this video.
