Optical Pumping - an overview | ScienceDirect Topics- pumping source in laser color ink ,Another source for optical pumping is the semiconductor diode laser.. These lasers are especially useful for pumping solid state lasers, like Nd:YAG.. Compared with flashlamps, diode lasers offer a better match of the output spectrum to the absorption of the material.. This leads to increased efficiency and results in a smaller, lighter system..Laser pumping - WikipediaLaser 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..
Introduction to Lasers.. In popular science fiction videos during the 1950s, monsters were often portrayed that could emit lethal rays of light from their eyes (Figure 1), but until the invention of the laser, such concentrated and powerful energy beams were only fantasy.. Now it is possible to modify, probe, or destroy matter using the highly ..
Optical pumping: light is used to raise the atoms to higher energy states.. Chemical pumping: chemical reactions are used to raise the atoms.. Electrical pumping: A strong field is applied to the atomic system with the use of high voltage power supply.. The high energy electrons collide with the atoms and transfer their kinetic energy to the later..

The pumping light source can be any of several different lasers, including a nitrogen laser (3371 Å), a frequency-doubled Nd:YAG laser (5320 Å), or an XeCl excimer laser (3080 Å).. The only requirements are that the pumping laser must be of a shorter wavelength (i..e.., higher frequency) than that of the dye laser, and that the gain medium is able to absorb light at the pumping laser wavelength..
The 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..

A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation..The word "laser" is an acronym [1] [2] for "light amplification by stimulated emission of radiation"..[3] [4] [5] The first laser was built in 1960 by Theodore H.. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and ..

As most laser dyes have very short fluorescent lifetimes, a longer pump pulse is desirable as this leads to narrower linewidth.. Litron’s telescopic resonators have longer pulse durations, typically 8-10ns.. OPOs are solid state tunable sources, typically with visible and IR outputs, that require a uniform pump beam with low divergence..
