Unit –I LASER Engineering Physics - Applied Physics
Xenon flash tubes are used for optical pumping. Since these materials have very broad band absorption, sufficient amount of energy is absorbed from the emission band of flash lamp and population inversion is created. Examples of optically pumped lasers are ruby, Nd: YAG Laser ( Y3 Al G5 12) (Neodymium: Yttrium Aluminum Garnet), Nd: Glass Laser ...

Since it emits only for a short time and only during sample measurement, it has a long life. The sample is only irradiated with light at the time of measurement.

Xe short-arc lamps come in two distinct varieties: pure xenon, which contains only xenon gas, and xenon-mercury, which contains xenon gas and a small amount of mercury metal. Xenon-mercury
