Optical pumping of Rubidium Dr. Johannes Recht and Dr. Werner Klein, LH-Contact 1, (1991) pp. 8-11 Optical pumping is a process used in high frequency spectroscopy which was developed by A. Kastler. It allows the spectroscopy of atomic energy states in an energy region which is not accessible by means of direct, optical observation.
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. In this condition, the mechanism of stimulated emission can take place and the medium can act as a laser or an optical amplifier. The pump power must be higher t
Ruby laser definition. A ruby laser is a solid-state laser that uses the synthetic ruby crystal as its laser medium. Ruby laser is the first successful laser developed by Maiman in 1960. Ruby laser is one of the few solid-state lasers that produce visible light. It emits deep red light of wavelength 694.3 nm.
optical pumping, in physics, the use of light energy to raise the atoms of a system from one energy level to another. A system may consist of atoms having a random orientation of their individual magnetic fields. When optically pumped, the atoms will undergo a realignment of individual magnetic fields with respect to the direction of the light beam; that is, there will be a rearrangement of ...

Alkali-metal atoms are often used for optical pumping because they have a single valence electron and thus resemble a hydrogen atom. The photon wavelength needed for optical excitation is in a convenient range of the spectrum, where diode lasers are available. However, alkali-metal atoms have a nuclear spin, which complicates their level structure.

Answer: Chemical pumping in a laser is when a chemical reaction excites the electrons which power the laser light emission. Fire glows, right? This is a chemical reaction making light.
(C) Optical pumping scheme and vibrational wave functions. The vertical black boxes indicate the spectral bandwidth of the laser. In (B) and (C), arrows indicate the optical pumping for ν X = 4 molecules. The most probable optical pumping scheme is to reach ν X = 0 through excitation into ν B = 1.
with the optical-pumping time between the two hyperfine ground states, the optical pumping can alter the ground-state populations and therefore the absorption spectrum of light by the atoms. In this paper we present some considerations of hyper-fine optical pumping in alkali atoms within the context of laser-pumped microwave frequency references.
Optical pumping in lasers involves at least three different energy levels. In the simplest case, laser-active ions are pumped from their ground state to a higher-lying level, from where they undergo a quick radiative or non-radiative decay into an excited level with somewhat lower energy.
Semiconductor lasers for optical pumping and fast optical saturable absorbers, based on either semiconductor devices or the optical nonlinear Kerr effect, have dramatically improved these lasers and opened up new frontiers for applications with extremely short temporal resolution (much smaller than 10 fs), extremely high peak optical ...
The optical pumping of Dy:PbGa2S4 laser was performed by flashlamp pumped Er:YLF laser at 1.73 μm wavelength. The compact 60 mm long Dy:PbGa2S4 laser oscillator worked in free-running mode with the repetition rate 1.5 Hz. The output energy was 5.1 mJ in 80 μs long pulse at 4.3 μm wavelength.
Optical Pumping is a method rst developed by Alfred Kastler1 (who was awarded the Nobel Prize in 1966), that has become a widely used technique in experimental physics ever since. Optical pumping is a process in which electromagnetic radiation is used to pump electrons into a well-de ned quantum state.
It is shown that laser saturation spectroscopy with optical pumping leads to several novel effects. Saturation signals of anomalous sign and amplitude dependent on laser polarization, reduced ...
Answer: It is the use of light as the energy source which raises atoms to a higher energy state. Different laser media use different types of pumping. For example, one way to pump a pulsed laser is with a Xenon flash lamp.
Optical Pumping: Three- and Four-Level Systems. In a simple two-level system, it is not possible to obtain a population inversion with optical pumping because the system can absorb pump light (i.e., gain energy) only as long as population inversion, and thus light amplification, is not achieved. Essentially, the problem is stimulated emission ...
