This has become a frequent problem in the Bay Area of North Cal. I’m not smart enough to be an engineer, but I would think somebody should be trying to develop glass for the cockpit area that is capable of reflecting the laser beam back out with close to equal force as it is absorbed by the glass dome. This repelled or bounced off beam should be sent back down at roughly the same trajectory as it was fed to the glass. This would be poetic justice if ever perfected, where a joker shining a laser gun at a jet would then himself become blinded by that boomerang beam. Okay, maybe it’s still science fiction for this week, just you wait.

Good idea Lee. I would be surprised if no one has thought of it. We have had thin film optical coatings for at least seventy or eighty years. One of the pioneering companies was/is in Santa Rosa, your neck of the woods? For this threat I’d look for a tunable optical coating coupled to a cheap spectrometer to identify the frequency of any radiation of sufficient power to be dangerous, and apply a potential (voltage) to the coating, probably sandwiched like safety glass in the cockpit windows, to adjust its thickness to reflect the energy. The protective coating might simply be applied to goggles, but goggles or windows, the idea is reasonable.

We already have optical coatings that reflect most visible and infra red frequencies, but are transparent to an optical window in our sky that causes heat on earth to “see” the almost absolute zero temperature of space, enabling "Carnot" cooling of the space behind a window. Unfortunately, the building with the window to space would need to be extremely well insulated for the cooling effect to dominate the heating caused by air leaks around windows and doors. But optical coatings are widely used, and I believe some optical telescopes have tunable coatings already.
