all that for a weak laser dude u can buy a better diode for a portable

Please less talk, more action next time. ;)

Ok, I'm sorry, but this laser is waayyyy better: http://www.snotr.com/video/7618/Iron_man_laser_glove :D

actually 124 watt

2,3 volt 51 Amps makes 124 watt (not using calculator)


But he cant beat this one

7 minute video of a brick getting a bit heated up, come on SNOTR!

#5 the diode has less than 100% efficiency of course, and he appears to be getting about 1/3 watt per amp at the operating voltage. So even at 90 amps (his quoted full power rating) at the 2.3 volt operating level, which is 207 watts total input power, 60 watts is about right. For him operating at 124 watts input, his laser is probably putting out around 41 watts or so. But laser diodes are also not linear- highly dependent on temperature and power supply internal resistance.

You get a 60 watt laser for a 90A input??? For gosh sakes, that's enough to run most welders.

It's not like he is "popping" balloons like that other silly video. This one is way more powerful than that toy.

I would love to have seen him let loose a whole bunch of ants and watch them crawling all over the brick only to be vaporized by the laser beam, now thats a use I can foresee >:)

Next time show us what it does to your tongue, maybe then you'll stop talking so much

#5 the reason he only has 60 watts output and not 124 watts Laser output is due to the fact that the electronic circuits he has designed to create the Laser energy creates a huge amount of heat to be generated, which is why he has had to hook it up to the liquid cooling system, solid state systems are even less efficient, around 20 percent or less.

#1 You clearly don't know much about lasers. You can hardly find 2 watt portable laser diodes right now.
