Title: Optimal Stochastic Enhancement of Photoionization

Abstract

The effect of noise on the nonlinear photoionization of an atom due to a femtosecond pulse is investigated in the framework of the stochastic Schroedinger equation. A modest amount of white noise results in an enhancement of the net ionization yield by several orders of magnitude, giving rise to a form of quantum stochastic resonance. We demonstrate that this effect is preserved if the white noise is replaced by broadband chaotic light.

  • Dynamic optimization was used to investigate the optimal defoliation of salt desert shrubs in northwestern Utah. Management was formulated in the context of optimal stochastic control theory, with objective functions composed of discounted or time-averaged biomass yields. Climatic variability and community patterns of salt desert shrublands make the application of stochastic optimal control both feasible and necessary. A primary production model was used to simulate shrub responses and harvest yields under a variety of climatic regimes and defoliation patterns. The simulation results then were used in an optimization model to determine optimal defoliation strategies. Three questions were addressed: (i) Whatmore » effect do changes in weather patterns have on optimal management strategies. (ii) What effect does the discounting of future returns have. (iii) How do the optimal strategies perform relative to certain fixed defoliation strategies. Similarities could be seen in the influence of both the discount rate and the climatic patterns on optimal harvest strategies. In general, decreases in either the discount rate or in the frequency of favorable weather patterns led to a more conservative defoliation policy. This did not hold, however, for plants in states of low vigor. 34 references, 4 figures, 8 tables.« less
  • Excited states of Sm atoms are investigated by using multi-color resonance enhanced multiphoton ionization spectroscopy. Among the ionization signals one observed at 577.86 nm is regarded as the most efficient excited state if an 1-color 3-photon scheme is applied. Meanwhile an observed level located at 587.42 nm is regarded as the most efficient state if one uses a 2-color scheme. For 2-color scheme a level located at 573.50 nm from this first excited state is one of the best second excited state for the optimal photoionization scheme. Based on this ionization scheme various concentrations of standard solutions for samarium aremore » determined. The minimum amount of sample which can be detected by a 2-color scheme is determined as 200 fg. The detection sensitivity is limited mainly due to the pollution of the graphite atomizer. {copyright} {ital 1997 American Institute of Physics.}« less

  • Photoelectron spectra following 1s-inner shell photoionization in laser excited 1s{sup 2}2p {sup 2}P{sub 3/2} Li atoms were measured in the 90-100 eV photon energy range using the synchrotron radiation emitted by Super ACO. A very strong enhancement of the shake up correlation satellites corresponding to 1s3p {sup 2}P{sub 1/2,3/2} final ionic states has been found, leading to an overall relative intensity of the (n = 3) satellites higher than 65%, as compared to about 30% for Li atoms in the ground state. These new results confirm earlier observations of satellite enhancements in excited Na- and K-atoms and more recent calculationsmore » for Li atoms.« less
  • The gain achieved in lasing to the ground state following short-pulse field ionization by a pump laser is highly transient. It will usually persist for only tens of picoseconds because of the rapid filling and negligible emptying of the ground state. Employing a detailed atomic model of lasing in hydrogen, we show that the removal of ground-state population by an appropriate broadband ionizing radiation field can enhance and prolong the gain in such a laser. {copyright} {ital 1996 Optical Society of America.}
