Laser pumping - Wikipedia- pumping source preferred for gaseous laser is ,Laser pumping is the act of energy transfer from an external source into the gain medium of a laser.. The energy is absorbed in the medium, producing excited states in its atoms.. When the number of particles in one excited state exceeds the number of particles in the ground state or a less-excited state, population inversion is achieved..Laser Pumping - an overview | ScienceDirect TopicsThe relevant components of a cold cathode-type e-beam diode suited for excimer laser pumping are shown schematically in Fig.. 13..The e-beam diode consists of a cold cathode to which the pulsed high voltage (negative polarity) of 30 to 1500 nsec is applied, a thin foil anode, and a pressure foil separating the high-pressure laser gas mixture from the vacuum diode chamber..

The term in-band pumping is also often used in cases where the laser-active ions are pumped from the ground-state manifold (not being the lower laser level) directly into the upper laser level.. For example, this happens when a neodymium-doped laser crystal is pumped around 0..88 μm..

The HeNe, ion, molecular-gas, and excimer lasers define four of the most important classes of gas lasers in commercial use today.. Other successful gas lasers include the helium-cadmium (HeCd), metal-vapor, and nitrogen lasers.. Together, all of these gas lasers cover the spectrum from the UV to the far-IR (see Table 2)..
Depending upon the type of laser, the most commonly used pumping methods are listed below: a) Optical pumping: In this, the population inversion is achieved by means of light energy delivered from appropriate pumping source such as gaseous discharge or flash tubes.. For example, in ruby laser, xenon flash tube is used..

Heavy ion beam pumping of gas lasers had first been demonstrated in 1983 at the Munich tandem van de Graaff accelerator by pumping an infrared He-Ar laser with a 100 MeV 32 S beam (Ulrich et al.., Reference Ulrich, Bohn, Kienle and Perlow 1983)..
