Lasers have become an integral part of many modern applications in various fields. These applications employ variety of Lasers such as gas, diode, Solid State, Dye, Metal Vapour, etc. Of all these, the Solid State Lasers (e.g. Nd: YAG, Nd: YLF, Nd: Glass, Ruby, etc.) need an Optical input (pumping) in order to derive the Laser beam. The optical input is given by Flash lamps and CW arc lamps, which are high intensity gas filled discharge lamps. The gases typically employed are Xenon & Krypton since the spectral characteristics of radiation emitted by these discharges match well with the absorption bands of the active media.
