... the CO2-laser is a 'gas-laser', where the gas mixture is energetized by high voltage and moving electrons, ionising some of the gas molecules, which starts the 'LASER'-effect between the two end-mirrors, where one of them is semi-transparent, so a part of the generated light can escape as beam.
In the diode a really small semiconductor crystal with special doping generates light from moving electrons in the crystal, what's resulting in a similar light emission.
The generated wavelengths are different (10640nm from the CO2, 405nm to 975nm from the typical diodes), so this two types of lasers behave very different with different materials.
There is much more about lasers, but this is an essential part of the 'learning curve' ...

I've checked that site out before. Thanks. I looked the site over again and was checking out the laser shielding. The price looked very reasonable, so I put one in the shopping cart and went to their checkout page and was shocked to see the shipping costs for USPS for a piece of 12" x 12" shielding!
$50 to ship via US Mail is OUTRAGEOUS!!
