60 Watt IR Laser Diode Does Some Burning

A 60W 808nm IR diode based laser is used to burn through countertop material, tin can lids, and other materials.

so, is the laser diode the pump here, and the gain medium a type of glass? i.e diode-pumped solid-state? im having a load of trouble trying to find out if barcade scanners are diode-pumped solid-state lasers, or just laser diodes (as i understand laser diodes are not defined as solid-state lasers)

@calum591 This is just the output of the 808nm diode itself. I am not using a yag or other crystal. Some barcode scanners contain a very small hene laser tube, most seem to use a diode.

is there a color laser that works beter for burning if i had a 1w green 1w blue and 1w red what wold burn beter or are they all the same?

[billg519]

@ghostdawg2 Probably one of the best burners available would be a laser based on a 12x bluray diode. The 405nm violet beam will even burn white materials. I would probably pick blue (445nm) over green or red.

So, in your laser experiments, have you toasted any pixels on your camera's CCD, yet? Can you see the laser at all with your eyes?

[billg519]

@mraiford My cameras have done well so far. No fried pixels, yet. 808nm is seen as a dull deep red, but only try this indirectly with a well diverged low power source.

what for eye protection?

@ghostdawg2 blue+red+green=white

I wonder if that can pop a baloon.

@billg519 but green is more visible, and purple is almost invisible to the eye ;)

@jhawins

the actual color is light pink...i think

maybe the radiation light is messing with the camera

[jhawins]

And why is it so unfocused? I mean I know it's sick as is! But why not focus it to say .5-1 mm?
