interaction of neutrino with laser

[jayaramas]

i want to know how neutrinos interact with strong beam of laser , if laser beam is going in opp direction along a neutrino beam?

Neutrinos do not interact with electromagnetism at all. They have zero charge. And while it's theoretically possible they could have a magnetic moment, it would have to be extremely small, and one has never been observed.
