WebLight is involved in covering a wide range of frequencies. Focusing: As the laser is highly directional, so we can focus it on a very sharp spot. As light is divergent, so we cannot … WebThe coherent properties of light are described by temporal and spatial coherence. Temporal coherence is characterized by coherence length, L coh. L coh expresses the propagation distance over which coherence of the beam is kept. Temporal coherence also tells us how monochromatic a source is.
