Electric discharge pumping in laser
WebIn the fibre laser, the lasing medium is an optical fibre doped with low levels of a rare earth element, such as yttrium, erbium or thulium, which determine the wavelength of the output light. Diode lasers are used to couple infrared light into the cladding of the doped fibre and act as the pump source. This pumping action excites the dopant ...

WebJun 18, 2024 · Population inversion in nitrogen laser. Population inversion in nitrogen laser is achieved by electric discharge pumping. In this case, voltage is applied across the electrodes of the gas discharge tube which is filled with a low-pressure gas mixture known as the gain medium. The applied voltage produces an electric field within the tube.
