Special properties of laser light
WebFigure 1: A prism is inserted into a spatially coherent laser beam, generating an interference pattern on the screen. There are two very different aspects of coherence: Spatial coherence means a strong correlation (fixed phase relationship) between the electric fields at different locations across the beam profile. For example, within a cross-section of a beam from a … WebLaser light can cause significant hazards, particularly for the eye, but also for the skin, apart from fire hazards and others. Lasers pulses are often particularly dangerous, because …
