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

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.

#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.
