Hi! I have some trouble with atomic unit. I have a laser pulse with the wavelength of ##800 nm## at the
peak intensity of ##1.0*10^{14} W/cm^{2}##. I'd like to calculate the corresponding electric field ##E_0##. I use the formula ##I=0.5Cε_0{E_{0}}^2## and ##1 a.u.=5.14*10^{11} V/m## to obtain ##E_0=5.3*10^{-6}##, which is much smaller than the expected value 0.1.
Another question is about the energy spectra. It is written as ##\frac{\partial P}{\partial E}##. Is the P here means the probability density or the probability?
Thanks!
