while that works for low powered lasers, i believe these days most are directed by magnetic fields, much like the particle guns in side a television tube.

Photons don't have an electrical charge, you can't direct them with magnetic fields IIRC. The TV uses electrons, which -do- have a charge.
Right. A CRT uses an electron gun.
A laser mirror must be relective at the laser frequency. We used a CO2 laser to mark Intergated Circuit epoxy packaging (IC chips). The mirrors were (copper?) not good for personal use.
