the lipstick container looks like an optical trap for laser beams,
The two mirrors look like optical phase conjugate mirrors, precisely spaced to harmonically amplify each others complex portion of the wave equation, compressing the energy density of the laser into something enough to melt the door
TLDR non-linear optics
Also, i heard a rumour that the creators of this series based the physics on an alternate Riemann metric or something, not sure there, haven't learned that physics
