UV laser, ionising air

    I've noticed ultraviolet laser diodes have come out and I'd like to
    use a UV laser to create a path of ionised air along which a pulse of
    high voltage electric current can travel. I've heard of people doing
    it before so I know it's possible. I want to ask if anyone can suggest
    how many milliwatts of laser output would be required to ionise the
    air in this way. Also, how would the temperature and humidity of the
    air affect the ionisation? I realise increased humidity would aid the
    flow of electric current.

    Milliwatts? At least several million if not tens of millions.

    In other words this isn't going to happen with a UV laser diode.
