Default C-Mount Burning @ 1110F, 599C !!!

Link to my video on youtube. It's 24mb so I can't upload it here.

YouTube - 1000DegLaser

I used a wood shim that I had previously burned a hole through to hold the end of the temp probe. I did this so it would shield most of the scatter off of the temp probe's metal end which is quite burnt now. I'm sure the temp is actually higher and could be more precisely measured with better equiptment but it's still pretty cool.

Neat video!!! First I've seen with temperature measurement. Very interesting. Can you tell us more about the laser? Hoiw many watts, what wavelength, fac, what lens used, what driver? Is that really a single 9V battery powering the whole thing in the video? How long does the 9V last, or is there a bench power supply as well? I usually use li-ion or lipo for larger burning lasers. Never even tried a 9V... Nice work.

Rather than type all the info again I'll just post a link to the thread that has the info your looking for here

http://laserpointerforums.com/f42/5w...-ir-41236.html

Prior to that thread I have made a couple changes to the setup. First I swapped the 12v cooling fan for an 8.5v from a ps2 so I could seperate the power sources from the laser and fan.(also longer run time from the 9v battery) I have also found a better lense combo, one for burning and one for long range collimation. To burn I am using two coated lenses from 20x dvd burners, this gives me a very small dot size and maximises energy density. For long range collimation I hacked an old barlow lens assembally from my Tasco telescope 2.3x barlow. To make this work correctly and give me a circular output vs a small line I added one of the glass lenses(shown in the other thread) just before the barlow and a double aspheric lens after the barlow. To get proper collimation it takes a bit of trial and error. It's time consuming because the light is IR and must be viewed through a digital cam display. The length of the barlow lens assembally is 7 1/2 inches, so when mounted it looks a bit like a narrow telescopic camera lens, pretty cool!

Thank you for your interest billg519! Happy lasing!

Thanks for the link and extra info! I've used the two lens from DVD burner setup for burning too. Your long range collimation setup is very interesting and sounds well thought out. Do you lose significant power going through so many lenses, or will it still burn well at say 20 feet across the room? I'll have to try something like this.

Bill.

For long range I remove the two dvd lenses so it's just a three element setup all glass. The barlow setup acts like a beam expander so its difficult to get it focused to a small dot at a close distance. At 20 ft I could achieve a minimum dot size of 1/4in but at 100ft I can get a dot size of 1/16in. Even at a 1/4 in dot size it will melt plastic. The only camera I have has a decent IR filter so its hard to pick it up at a distance. I have to set it and then walk to the location of the dot to measure it's size. I couldn't tell you what the power loss is b/c I don't have an LPM yet, but it looks to be a small percentage. I'm sure somene else has tried something like this before, I just havent seen it yet.

Thanks. The barlow setup makes it look like quite an impressive device overall. LPM's for multiple watt lasers do turn up occasionally. I lucked into a Coherent 210 and head one day on ebay and won it. Goes up to 10 watts. Older analog device, but very handy for an experimenter.
