Find Optic Laser Material That Responds to Perpendicular & Parallel Light

[flux!]

I am looking for group of material that behaves according to the following:

(1)
When a certain laser light passes perpendicular to the surface of the material it enters and exits unimpeded

(2)
However, when another laser light (with direction parallel to the surface) enters the material, the perpendicular laser light is blocked

Any help on what type of material is this? (e.g. semiconductor polarizer, photonic crystal, high Raman gain material, i don't know really)

Thanks in Advance!

Usually those properties are accomplished by applying an approprite optical coating.

Thank you for the response Dr. Courtney, can optical coating make the above properties dynamic, meaning when number (2) of the above is switch off we recover number (1), then back again.
