Face it, this problem isn't going away. With higher powers and more collimated beams as technology explodes, the threat will get worse .... for a time. Stiffer sentences may deter some, not enough to really matter. Eventually the thrill will wear off as most everyone, by then, will have played with a laser and shone it skyward.
Until then though, why not protect yourselves on the FD with simple theatrical gel filters? I am aware of the risk in altering the color view through the forward cockpit windows, but also understand that those windows are mounted at an angle where ground based laser beams have trouble entering.
It's the side windows where most laser strikes enter from, I am assuming.
This video demonstrates that several colors of gel filters will completely absorb green laser light.

These filter sheets come in sizes that can be easily trimmed to cover the entire clear view windows. They should cling to the glass via static. Just toss it up there in known high threat environments.
There's a company called Rosco that sells these filters in any color you can imagine, sheet size is around a 2 foot square.
