Hello everyone,
I'm completely new to the world of lasers.
I'd like to built a laser cuter to cut thin pieces of metal and wood. I Have a few questions that have been bugging me about laser and power ratings etc.
First off, I see a lot of 5 Watts 808nm laser diodes on eBay for 120 US dollars or so .
Does 5 watts mean that the laser beam deliver 5 watts of power or that the diode consumes 5 watts?
Second , is this the wavelength and power I need for the given intentions I have?
Third, what kind of optics do I need to buy? And am I getting something wrong or in theory I can focus the beam to an infinitely small point and so I could cut through pretty much any material so long as I focus the beam properly?
Thanks!
Ethienne.
