I need to use the low pressure region inherent within the cross section of a laser beam for a project. However, I don't know how to calculate the necessary laser power to generate a sufficiently low pressure.

The topic is briefly dicussed *here*, but I see no relevant equations.

I have no idea how to approach the problem of calculating the temperature of the air inside the beam. I would appreciate any help.

Thanks,
