Basic Operating Concept

Electrons moved from ground state to higher energy state.

When electrons descend to ground state, photons emitted of specific wavelength.

Photons oscillate in mirrored resonator

Increases intensity by stimulating emission of additional photons of same wavelength and phase.

Photons escape via output coupler

Irradiance (Power Density)

Expressed in W/cm2

Function of the beam power divided by beam area

Beam area a function of:

Beam size at aperture

Beam divergence

Distance from aperture

> irradiance > potential hazard
