i got one but it costs about 10,000$
current rate is 1000$ per wat

it will be hand held as long as your hands can hold over 100lbs.

if i can buy a 1.9 w handheld laser that fits in my palm for 250$, then i should be able to buy a 5-7 w for around 600$ the size of a maglite. whats the probl. does technology not exist?
 
6W laser will cost no less than 1,000$ the tech exists your wallet is not large enough.
 
dun worry about money. How large would a 5w be.Who can build this ?

The price per mW doesn't work like you think. A diode can only take so much. After that you need a new diode that is more expensive.
By your logic, I can buy a 3V button cell for about 30 cents, so I should be able to buy a battery of the same size but puts out 300V for $30

understand
just looking for someone who can build me a 5w+ handheld
what the problem is

It is entirely possible to have a 10 watt "handheld" laser, but no less then five or six pounds. The way I see it, there are three ways to get your desired power level without buying an enormously expensive lab laser.

1) 445nm blue laser diode array. Get 6+ M140 diodes running at ~1.5A each, and use knife edging to combine them into one beam. Use a large Li-ion battery pack or other lithium-based batteries (Like lithium polymer for higher currents). Use flexmod P3's to power the diodes, place all the diodes in a drilled chunk of aluminum, and mount it in some sort of rifle-shaped enclosure, with the batteries in it. (or use a backpack power supply). Still technically "handheld", but would cost around a thousand dollars AT LEAST.

2) Do the same thing, except with high powered IR diodes (this would be far more difficult and would produce poor beam specs).

3) Do as Kiyoukan suggested, and use a very high power IR diode. This would likely need a massive heatsink or TEC, or both, and would have similar divergence (past the focal point), to that of a flashlight.

All of this being said, you don't seem like the type I'd trust with such a powerful and dangerous set up.
