Hi,
I'm brand new to this forum and any sort of laser science. I'm trying to educate myself as I work on a project that I'd like to use lasers in if I can. I want to make a laser clock. Pretty straight forward, I figure the minute hand is one color laser and the hour another color. However, with my (very) rudimentary knowledge of lasers, different colors means different visibility in air. I'd like visible lines from the center point to a specific distance away from the center (to make the hands). I plan to use either mirrors or a prism to end the beam unless theres a way to make a laser taper off the end. I've seen projection clocks, but I'd like to make an installation where the lasers are situated on a center piece that (with other circuitry and mechanics) turns to the time, separate project. Would this mean I need another medium for the laser to travel through to make the beam visible? if so what sort of medium, I would need this to be mostly or semi transparent to see mounted artwork behind it in the day or when the laser is off. So to get to my question: what color laser is most visible, are there such color (and power) lasers that are either prefabricated in a square or flat/rectangular shape which can be modified to be controlled with a separate IR controller, and if theyre not prefabricated whats my best bet in terms of power, color, components, etc?
Thanks for the help
