Fiber optic cable to laser projector? Answered

I purchased a "Mr. Christmas" Laser (green) Outdoor Holiday Projector to add to my holiday lighting this year. Being rightly concerned with theft if I was naive enough to leave the projector outside, I thought of using fiber optic cable attached to the laser lens housing (still haven't worked out how I would accomplish that), and routing it from inside the house to a point outiside where the cable end would project on a wall or my garage door, providing a show (sans sound), but protecting the laser projector from theft. Is my idea feasible? If not, I'm open to suggestions. Thanks.

I didn't know where else to post this - let me know if I should repost it elsewhere. I'm looking for plans{?} for a laser beam "expander" that doesn't cost hundreds of US dollars. {I'm on a BUDGET.} Short version of why: If you read my profile, my hobbies include 'Kite Aerial Video'. Basically, it's aerial video shot by a camera suspended from a kite line. {Usually done that way versus putting the cam directly on the kite.} I'm 'researching' using a laser {or lasers} for night time illumination with a miniature low-light video camera for wildlife / nature observation. Most of the stuff I need - including the vid cam and laser - aren't too expensive. However, the cheapest expander I have found was over $300 USD. I was hoping I could find something cheaper here. I know someone who did something similar with a Generation 3 night vision monocular. However, a Gen 3 night vision imager is too expensive for me. And for KAV, the cheaper Gen 1 & 2 imagers won't work. Thanks in advance. -Allan, aka RocKiteman N.E. North Carolina, USA

Project a laser pointer beam down a medium that will allow it to shoot out the other side.

I am working with some models and am incorporating laser pointer as 'phasers' and am currently using  mirrors to allow for that function.  The areas are tight and some spaces will not take mirrors but I was wondering if there was something like fiber optics or another medium that I could use to let the beam travel down and exit out.  I have seen fiber optic kits for models but the light stops at the end of the cable so I am not sure if that is a good medium.  If fiber optics are an option, how do I size the cable for the laser?  Does the beam strength decrease going through a medium?  I know for fiber it can be miles but just wondering.  I did read the comment about the guy wanting to build the glove but my request is much simpler with hopefully easier details. Thanks Andrew

Laser square projector

I work in a manufacturing facility and we've got a lot of forklifts that are buzzing around everywhere all the time. there's an initiative to make it safer for forklifts to interact with pedestrians. one of the ideas someone had came from another facility where they have these blue spot lights on top of the truck that project a blue dot in front of and behind the truck. you see the blue dot and you know a truck is coming. there's some concern that this might get missed by a pedestrian. a thought came to me, being a nerd, that we could use something maybe a little easier to see. I looked in to some disco type laser displays that you can display custom graphics with, but there's concern about how sturdy they are or how long you'd actually be able to use one (whatever it is would basically have to be on almost 24/7). we've got several Motorola barcode scanners, and the long range models (mc 9190) have a feature where it projects a red square to show the area where the scanning will take place. it's a solid red square, not just a perimeter, that scales up with distance (it's like 4"x4" if you're within 2' and goes up to a pretty large size the farther out you're pointing it). These scan guns are way more expensive than this project calls for of course. Does anyone know of a source for JUST the imagers for these things? or could anyone suggest a way to replicate the effect...a big red square on the floor, with other equipment. needs to be able to run for a long time, hopefully could be powered by a 24-36v DC source, possibly motion detection (though not really necessary)
