what will it take to build one? i want to use a high powered laser to field dress wild game and live stock. this isnt a joke. i want to build a laser that will actually cut and burn flesh at close distances... no more than 5 meters. soo... what's it gonna take?

ok.... whats the highest powered laser i can get my hands on to experiment with? i have a brother in law that is getting his phd in physics. thought this would be a fun experiment to play with while he's in town for the holidays this year. gotta have something to play with before he gets here

It would have to be IR and still you wouldn't get enough power to "cut" like you want

i imagine ir lasers are not battery operated and are not very portable... sorry, im a total newb with lasers. is this the type of ir your talking about?


High Power laser modules, laser diode modules and circular, diode pumped laser modules, fiber coupled green laser modules, fiber coupled blue laser diode, fiber coupled violet laser diode modules, Sanyo, Nichia blue laser diode

You could probably make do with 20W. It would be slow and smelly, though.
Diodes of this power level are available.
However, you run into problems when you realize you need active cooling and a portable power supply that can support it.

With enough $$$ and some ingenuity you could probably pull it off but something like this would cost something in the thousands.
Not to mention, it would be a pain in the ass to haul around a 40+lb laser system with power supply on top of your 30+lbs of other hunting gear. And a 1% reflection to your eye would cripple your vision in a hurry.

Use a knife.

Find out what type of laser a surgeon uses for "bloodless" surgery, ie, LASIK EYE SURGERY. That should do the trick for ya, but I don't think that it would be very compact or portable.
As was mentioned before, use a SHARP knife ................. rob

Sounds like a solution waiting for a problem. You can try making one of those lasers on Amazing1 or buy a CO2 laser and try to make it man-portable, but I'd just stick with the knife. None of the hand-held lasers you'll see on this forum are even close to that capability.

Nah.. its gonna be very difficult. I can imagine it would be possible to get a 100W-ish CO2 laser powered from some batteries in a backpack. In short bursts cooling might be entirely doable.

The whole thing would be heavier than a bundle of RPGs though, and probably just brand whatever you shoot it at. Since the damage is entirely thermal, i reckon you could easily burn an inch deep hole into a deer, and it would walk away with an instantly cauterized wound. Throwing the battery pack at it would probably stand a better chance of killing at 5 meters distance :D

ok... i was kinda joking about field dressing....actually i am and im not. i guess my main goal here is to play with lasers. see how far i can push one. im normally in to philosophy and home audio... lasers have diffidently sparked an interest. any suggestions for a portable laser(diy is cool too) that will knock my socks?

I would recommend buying one of the 1w+ 445nm lasers the people on the forums build to sell. Check out the Buy/Sell/Trade forum. They are better than most of the ones you can order online. I run a 50w c02 laser etcher/cutter at work and while it burns all kinds of stuff, it does have it's limitations, and it's not visible so that takes away some of the wow factor. (also most of the things it burns besides wood and granite etching really stinks) The oem laser unit alone is/was ~$10,000 and isn't something I would want to make portable. Funny thing, it wasn't until I started coming here and researching and getting some moderately powered (200mw+) 532, 445, 650 that I really started paying attention to SAFTEY, and believe me, I'm not really the safety type if you know what I mean, but one wrong move with these things can land you in jail or cause permanent eye damage. If you wanna burn go for the 445, if you want awesome light get a 200mw+ 532, they appear roughly 3 times brighter per mw just because of the color. Get some good goggles too, even diffused light up close can hurt ya man. :gun:

Get a 200mw red and some safety goggles to get your feet wet. Field dressing animals using a laser is possibly the worst application for a laser I have ever heard of. Have you ever smelled burnt hair?!

You might want to spend 2 minutes researching what portable lasers are capable of before deciding what you want to do with one.

Even at this level, it would be like trying to cut a game or livestock hide with the tip of a soldering iron.

And AFAIK, those designs can only produce short pulses, not continuous beams for minutes at a time like you'd need to get the belly-cut on a deer or a cow or whatever.

Members here have produced battery operated IR lasers about the size of a "Bazooka" with a portable battery box, and a PVC pipe to hold the laser that used surplus industrial laser tubes, but all they can do is fire for a few seconds and produce a burnt spot on a piece of wood from across a room.

You'd need something like a 20W or higher industrial CO2 rig like is used to engrave or cut steel. Assuming it was up to your abilities, it would be hand-held, but tied by a fiber optic cable to something the size of a large generator box, a cube roughly 3 feet on a side.

And even then, it would cut poorly, because while such a laser can blast or vaporize metal, it would have the large wet mass of the animal's flesh behind the skin and on all sides sucking away the heat, and/or making steam and smoke to diffuse the beam.

To see what it would be like to try and skin an animal with a laser, just get a propane torch, MAPP gas rig, or an oxy-acetylene rig, turn the flame to it's hottest and tightest point, and try to "skin" the animal with that.

The results will look about the same. A stinky smoky mess. :D

I know it seems like a smart-ass answer to post a picture of a knife, but it's infinitely more practical.

To "knock your socks" off at a reasonable price, I'd spend about $200 or less on a 532nm DPSS green handheld laser that's about 200-400mW in power from one of the reputable sellers. It will go for MILES in the air at night. The beam will be visible at short range even in full daylight. You'll be able to light matches, pop balloons, and burn through stuff like electrical tape and CD/DVD plastic cases.

Buy safety goggles with anything over 5-10mW, two pair for you and your brother to wear when playing with it. One flash reflected off of a piece of glass, or smooth metal surface etc. can leave a blind spot in your eye for life. No joke.
