ionization energy - Can a powerful enough laser ionize nitrogen in the air along the laser's beam?


Okay I apologize in advance for not posting an equation or more info, but due to my lack of experience, I'm just not arithmetically inclined enough to work this out myself.



If any of you feels so inclined to humor my ignorance, please discuss your thoughts on any of the the questions below.


It was mentioned on another thread that to Ionize Nitrogen with a laser, it takes approximately 1400 kJ/mol and that the wavelength needed to do so was 88 nm to ionize a single nitrogen atom.




  1. Does the required wavelength of 88 nm change when ionizing more than one atom?




  2. What kind of energy are we looking at to potentially use a laser to form a path of ionized air across a room?





  3. Is there a way to calculate how much length of the air will be ionized along the beam in relation to the laser's energy?




Even if you don't have a direct answer, please reply with your thoughts.
