Continuous vs. Pulsed Lasers
Thinner pulses give higher peaks for same average Power.

Divergence of the Laser Beam
See equation for calculating diameter of beam at distance r from the laser.

Specular (Mirror) Reflection
Specular reflection (left illustration) retains the columnar beam, and therefore, intra-beam exposure.
