HIGH RESOLUTION LASER SPECTROSCOPY IN COLD SUPERSONIC MOLECULAR BEAMS COOLING, REDUCTION OF DOPPLER WIDTH AND APPLICATION
The cooling of molecules during the adiabatic expansion of supersonic seeded molecular beams is reviewed and illustrated by the example of NO -molecules. The reduction of the Doppler width by collimation of the beam and the cooling to low rotational temperatures brings a significant simplification of the complex NO -absorption spectrum and allows its assignment. The measured rotational tem...

متن کاملLaser Acceleration and Laser Cooling for Ion Beams
Cooling and acceleration of ions by lasers has gained increasing attention over the last years. The common interest is to further increase the luminosity of ion beams, either by shrinking the phase space occupied by the beam, or simply via increasing the number of particles. Recently, laser cooling has demonstrated ion beam crystallization as the ultimate reduction of the beam temperature. On t...
متن کاملPaired atom laser beams created via four-wave mixing
Sources of matter waves gained a dramatic improvement with the achievement of Bose-Einstein condensation (BEC) in dilute gases and the development of the atom laser [1]. Like optical lasers before them, atom lasers can produce Heisenberg-limited beam profiles and promise high spectral density through their dramatically lower linewidth. Another exciting possibility resulting from having such a c...
متن کاملLaser cooling of electron beams for linear collidersl
A novel method of electron beam coofing is considered which can be used for tinear co~ders. The electron beam is cooled during co~sion with focused powerfti laser pulse. With reasonable laser parameters (laser flash energy about 10 J) one can decrease transverse beam emitt antes by a factor about 10 per one stage. The ultimate transverse emit t antes are much below of that given by other method...
