I have been doing an experiment using a co2 laser. One of the procedures is the find the best gas mixture and explain why. I have found the best misture to be 8 parts co2, 1 part n2 and 1 part He, which i have researched and my sources show this is correct. However i also have to explain why, but everywer i search i just find very vague explainations on how the laser works, and a load of crazy people building their own and burning things!
I was hoping to find a more detailed explanation into how the gases affect the output of the laser. So if anyone could point me in the right direction id greatly appreciate it.
