Well, my jaw just hit the floor..
« on: March 31, 2017, 04:14:43 AM »
I was just nosing around on mouser, and I came across these diodes for the fantastic price of $31..
They are pulsed NIR diodes @ 905nm (pretty sure thats the wavelength commonly found in police LiDAR systems actually) with peak outputs of 75W. (absolute max of 90W in the datasheet)
They'll suck back a whopping 40A of current. These sound amazing lol. I'm just wondering what the he** I'm playing with 3.5W for when I could be cutting some serious sh**! And just think if you threw a crystal in front of it to double it up to 452nm, that would be a seriously bright blue laser. (or maybe it would vaporize the crystal... who knows, could go either way  :P )

Would obviously need any and all safety precautions associated with co2 tubes however, like fully enclosed key-interlock, and viewable only by CCTV, for example, but I'm having a hard time believing the price of these.

Don't need a whopper for that   1 watt job will do it.:)
.
Lasers are wonderful machines..not ONLY  can they cut a finger off BUT  they can also cauterise it at the same time.....

SAFETY -  IS NO ACCIDENT

It's a pulse laser, if you run a 50nS pulse width at 1kHz it's going to be outputting less than 10mW. Not too spectacular.

The effective power is 0.005% of the peak output, so you would need 50kW at that pulse rate to match a 2.5W laser and that's not even considering the wavelength. I doubt it's very useful at 905nm.
