|100 Watt Diode Laser -   2002/04/10||Viewed 437 times this month, last update: 2003/06/12|
|Yesterday Chris Bell and
I bought a new laser from the UCI salvage yard. This is
added to our first 240 Watt CO2 Laser Cannon, bought from the
same place. Supposedly it's fully operational, it comes with
two diode heads (Deep red, and maybe Green or Yellow), and
the huge power supply.|
The power supply is a cube about 2 feet to a side. It takes
120v at 30 amps, and needs low pressure nitrogen for some
reason. It comes with integrated liquid cooling for the
head, and circuits for continious output and pulsed, with a
nice waveform generator for pulsed mode built in.
See the first firing at 100 Watt Diode Laser Test Firing 1.
Here is the whole thing, in the back of my truck. The big box is the power
supply, and the two heads are the black boxes on top. The one pointing
front is connected to the cooling/power umbilical. The grey box at the top
right of the power supply is the waveform generator.
This is the warning sticker on the second head. Nifty eh?
Here are the power, cooling, and Nitrogen connectors on the back of the
second head. The two bottom are cooling in and out quick disconnects,
the top, brass fitting is the Nitrogen quick disconnect, and the two silver
posts are the power connectors.
Here is the first head connected to the feed umbilical.
A closeup of the front of the head. Just a normal fiber connector.

Matt Bell (2002-04-10): Setting up your own star wars defense shield?
I like the new design!
Erik G. Burrows (2002-04-10): Nah, defense is best left to the mote. :-) This is just for
scaring the crap out of people.
Jon (2002-04-11): When do we get to see it burning through walls?
Erik G. Burrows (2002-04-11): Give us a couple of weeks Jon. We need to figure out how
it works first, and then we need to set up a first
experiment. Rest assured, pics of that experiment will be
JMB (2002-04-24): I think you should unveil it at the premier of the next Star Wars movie. I'll be standing in line.
jaguar (2003-06-09): hey guys, your doin a nice work... im a fan of lasers and all its amazing capability.. its so unique. i been wanting to have one of those toys someday... but right now i am wondering what laser could be the best for cutting holes through big stones. my friends and i likes very much goin out to remote caves hunting for hidden treasures and precious stuffs. i have in mind the use of laser in making our way in... but i need it to be portable and handy... what might be the right choice? CO2laser or something else that suits me needs... hope you can help me. -jag
Erik (2003-06-09): Jag, unfortunately even very large lasers rarely have enough power for mining operations.
The biggest lasers I've heard of are the size of warehouses, and are used by the military to weld steel battleship armor that is up to a foot thick. Certainly one of those could help with rock drilling, but it's not terribly portable.
jaguar (2003-06-11): thank you erik, well i see. i'll just think of something else by now. you just keep up the good work, i'll be stoping by someday to watch you blast through holes. or maybe you can make a laser that suits my needs... im just kiddn..
i think your cool,thanks -jag
Erik (2003-06-12): Thanks Jag, good luck with you treasure hunting!
TimLa (2006-04-04): Jag means well, but is suffering cognitive dissonance. Or something. You guys haven't posted in a couple of years. Dead?
Erik (2006-04-04): No, just inactive. The laser works though.
Mario (2009-01-29): Interesting
Rej (2013-01-24): I had an idea for jaguar's mining operations. If you don't mind a non-lasery solution, you might try a pressure washer. The industrial versions can cut through concrete using only water! It definitely wouldn't be practical, but it would be really cool. Of course you could also try a sledgehammer or simply pushing the rock out of the way...
Rej (2013-01-24): I just realized how old all these comments are. Talking to a dead crowd...
