CO2 head 350 W peak (new, but not working – needs power supply and electronics)
“Continue reading” for more details.
This eBay laser was hiding under laser printers! It is a new head for a class IV CO2 laser marker used to make high speed barcodes and product information on a production line. It has acoustic-optical control to manipulate the beam non mechanically. Rating is 350 W peak and 100W continuous. It is water cooled and is RF excited so it will be a bit trickier to get going. I hope that I will be able to drive it by a spark gap and tuned circuit to the appropriate frequency. Quick and dirty but high power and not that dissimilar to Tesla tuned circuits. I will need to get info on it before I plan further. Like all CO2 lasers it functions in the far infra-red at 9.1 – 11.2 microns. Compare this with the HeNe red wavelength of 0.640 microns or the Nd:YAG wavelength of 1.064 microns.
Smaller CO2 lasers are available in engravers or as the bare tube at about the 40 W level.
