Near Field Beam Profiles

By: :JIANSONG WU 0 comments
Near Field Beam Profiles

Beam profiles display a bell-shaped or Gaussian irradiance distribution at the focal point. As you move further away from the center of the beam the irradiance decreases: the larger the diameter of the beam, the lower the irradiance. However, as you increase the diameter of the beam the total amount of light increases therefore the total power increases.
