The Rydberg matter laser: excitation, delays and mode effects in the laser cavity medium

摘要: Temporal and temperature effects are studied in Rydberg matter (RM) formed from K atoms N2 molecules as the active medium a cavity. The function of this setup laser was recently described. Temperature-variation studies show that photons re-exciting RM clusters usually have longer wavelength than emitted stimulated emission process deficit is probably covered by background photons. Very long time constants observed after emitter changes indicate long-wavelength photon energy accumulated clusters. Long-wavelength modes located farther emitter. modal structure can be TEM01 or TEM00, clearly spatial rapid pulsing experiments. in-cavity chopped beam signal delayed approximately 50 μs. initial growth rate during chopping dependent. Tailing also chopping, but with spinning mirror does not any delay start lasing. conclusion delays exist process. broad intense band appearing at 11 000 nm shown to partly light range 3500–5000 nm, standing wave interaction grating surface (grating bands).
