  • Yes, one can modulate NTSC onto a laser beam, I have done this in the past with no problems whatsoever.

    Simply configure your laser to be modulated and provide baseband composite video.

    At the other end simply extract the signal, be sure you do not invert the signal and do get the levels correct.

    Due to the massive available band width a laser has video is not a problem.

    Enjoy.
