The document discusses laser components and properties including continuous versus pulsed lasers, divergence of laser beams, specular reflection, and nominal hazard zones. It notes that thinner pulses give higher peaks for the same average power in continuous versus pulsed lasers. For divergence, it references an equation to calculate beam diameter at a distance from the laser. Specular reflection retains the columnar beam shape.
