Having it UV does kind of make sense, more energy in a small area. Yesterday, i saw TI:Saphire lasers and regerative amplification, <10 femtoseconds and 5 mJ is 50 gigawatts according to wiki. I kind of get the method of streching the pulse, amplfying it, and compressing it back, does anyone...

Re: So if lasers are so cheap to build then....... i think for some, there either high effeciancy, or tuned really good. Some are also under military contract so they put the prices high, knowing theyle still buy.

no, only resistance and voltage.

my mm has a 10A limit, didnt know what setting to put on, and i decided to see how much my lead acid battery was giving to my electrolysis cell, i connected it directly to the battery, bad idea... Probe wires got hot, and a little insulation melted, but thankfully it still works =) In...

why would a UV laser be better?

Ok, I have been reading up on solid state lasers, and have a couple of questions: 1) say yout have a 100W 808nm laser diode. When it goes through a YAG crystal, it is about 20% effeciant, that means output is ~20W 808nm. When its put through a frequency doubler (KTP i think), it becomes...
