CO2 Lasers and Electricity


New Member
I was looking into building a CO2 laser within the next few months to a year and I decided first that I'd need to learn more about volts, watts, amps and ohms. I've got the general equations and stuff down, but I'm just trying to understand WHAT volts, amps and watts really are.

So far I have this:
Watt-Energy per unit over time.
Volt-(an amount of force)
Amp-(Current) How fast something passes a point person unit of time.
nm- This isn't the electrical part, this is for the lasers.
Ohm-(Resistance) Measure of resistance to electrical conduction.

For the laser part, I'd like to know how wattage/voltage affect the wavelength (nm) of a laser. It seems to increase, but CO2 lasers have insanely wavelengths. Does a higher one mean that it burns faster? I would think that lower would be better.

In the end, I'm looking for someone that's willing to maybe teach me a few things and if possible to find someone that has built their own laser before.

PS-I'm 20. I'm not gonna go around attacking people with lasers. =P


Eye see what you did ther
E = hc/wavelength. Smaller wavelength means higher frequency and greater energy.
