The optical energy from a laser diode is coherent. That is, optical energy is produced in an optical resonant cavity and this optical energy when released is highly monochromatic ; Also, the output beam is highly directional. 6 Optical Energy from the two types of Optical Sources . Optical energy from an LED is incoherent.
WebOptical output from a source is measured in radiance (B). Radiance is defined as the optical power radiated into a solid angle per unit emitting surface area. Radiance is specified in Watts/cm2/Steradian. Radiance is important for defining source to fiber coupling efficiency.
