Good Form scroggs!

i am wondering why the ac cockpit windows cannot be coated with the same material as military ac and equipment against laser.
In the military, many of the weapons systems use lasers for rangefinding and guidance, and I know the gunsights and windows/ports on tanks are coated to reflect the laser from direct and return, with no optical reduction.
They also use this coating on building windows so that a laser cannot be used to listen to conversations inside.

Edit: Found this on a lab website..

A laser is a light source that can be dangerous to people exposed to it. Even low power lasers can be hazardous to a person's eyesight. The coherence and low divergence of laser light means that it can be focused by the eye into an extremely small spot on the retina, resulting in localised burning and permanent damage in seconds. Certain wavelengths of laser light can cause cataracts or even boiling of the vitreous humor, the fluid in the eyeball. Infrared and ultraviolet lasers are particularly dangerous, since the body's "blink reflex", which can protect an eye from excessively bright light, works only if the light is visible.

egsc_h17....people pull them out of color laser printers..very powerful uncontained.
