5. Optical components for high laser flux
Optical components for power lasers must be made from materials that can withstand high levels of laser power without deteriorating, excessively absorbing laser radiation or inducing changes in optical properties. These materials are chosen according to the specific requirements of the laser application, including laser wavelength, output power, operating mode (continuous, pulsed) and operating environment.
5.1 Solid materials
Transparent materials used for high-power applications must have the lowest possible absorption at the wavelength of interest, and very few impurities. A great deal of data exists in the literature, but as we have seen, it can be difficult to compare results obtained by different laboratories, and manufacturing processes have a major...
