WebOptical pumping is widely used to prepare atoms, ions or molecules in a selected quantum mechanical state. This can be either a specific electronic state (like in a gas or solid state laser itself) or a magnetic state. The latter is a prerequisite for laser magnetic field measurement and for monitoring the lung with NMR/MRT techniques involving ...

WebApr 1, 2024 · Exciton–polaritons in optical cavities exhibit strong nonlinearities predominantly because of the third-order Kerr-like interactions mediated by the excitonic component. Under quasi-resonant excitation, depending on the energy of the incident laser, it results in the optical limiting or bistable behavior. The latter phenomenon is manifested … WebOptical pumping is important to a wide variety of applications from the laser, to precise measurements of atomic hyperﬁne level splittings and atomic clocks, sensitive …

WebSep 15, 2007 · Abstract. We have studied double-resonance optical pumping (DROP) as a function of the polarization combination of lasers, laser power, and the alignment of lasers in the 5S {sub 1/2}-5P {sub 3/2}-D {sub 3/2,5/2} ladder-type system of {sup 87}Rb atoms.
