Webthe wavelength is always greatest in the least dense medium, the frequency of a wave is not altered by crossing a boundary, the reflected pulse becomes inverted when a wave in a less dense medium is heading towards a boundary with a more dense medium, the amplitude of the incident pulse is always greater than the amplitude of the reflected pulse. WebJan 13, 2024 · Linear wavelength. Linear wavelength conversion occurs when the laser is used to pump a gain medium, usually a crystal, to a higher energy state. The excited electrons decay to a lower energy state by emitting radiation at a longer wavelength. By placing the gain medium inside a cavity a laser is formed. A well-known example is the …
