Amateur Lightwave Tricks

The tests include cloudbouncing, moonbouncing, laser radar and an infrared laser on an amateur satellite. See the Lasercom Manual and this paper for intros. Meanwhile, other amateurs are looking for alien lasers pointed our way."

  1. a comprehensive laser guide by lingqi · · Score: 3, Informative
    Since we are talking about lasers and LEDs etc, so unless everyone reading here knows *that* much about lasers -- i would recommend the following site for everyone:
    Sam's Laser FAQs

    I have spent days pouring over the mass abundance of information there -- and it has convinced me that building a kilowatt CO2 laser to burn though buildings really is something everyone should consider doing for fun.

    They're using a laser to create what looks like a star, above most of the atmosphere. Naked-eye visibility! I wonder how much modulation you could put on it for long-distance communication.
