Lasers against clear plexiglass?

[tsofian]

I had another nasty thought for the corridor into Prime Base. The security post has lasers. It might be vulnerable to attack by shape charge warheads.

What if there are a number of plexiglass panels that can be placed to block the passageway? They are almost entirely transparent to the laser's wavelength. They could be fairly thick, enough to stop most bullets and to prevent the movement of people, and to trigger the detonation of shaped charge rockets and such. The Type 3 laser has an E Factor of 700 per second, so it can basically vaporize a human target every turn.
