Green-emitting mercury chloride laser pumped by wide-band optical radiation

Abstract

Green-Schwarz action of Type IIB string on AdS 3 × S 3 is constructed via coset superspace approach. The construction relies exclusively on symplectically Majorana-Weyl spinor formalism, thus permitting it easier to prove κ-symmetry for on-shell Type IIB supergravity backgrounds.

Optical characteristics and plasma parameters of a blue-green exciplex lamp

“…The contribution of processes (1) and (7) to the intensity of the spectral band with a maximum at λ = 502 nm depends on the rate constants of excita tion and quenching of the state B 2 and on the par ticle concentrations.…”

“…The low frequency (a pulse repetition rate of no higher than 10 Hz) charac teristics of the lamps were also studied using external heating of the mixture to provide a desired mercury dibromide vapor pressure. It is of interest to see whether the mixture can be efficient at elevated pulse repetition rates (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12) under the conditions of self heating and also elucidate the physics of processes improving the energy parameters. To solve this prob lem, we in this work studied the optical characteristics and plasma parameters of blue-green exciplex lamps.…”

“…In addition, they are promising for solving agrophysical problems (such as the rise in the excitation efficiency of chlorophyll mol ecules and thereby in the growth rate of plants), pumping of solid state and dye lasers, medicine, and biotechnology. As a working medium, these lamps use the plasma of a discharge initiated in binary or ternary mercury dihalide-gas (neon, argon, helium, xenon, and nitrogen) mixtures [1][2][3][4][5][6][7][8][9][10][11][12][13].…”

Mechanism Enhancing the Emission Power of Gas-Discharge Lamps Based on Mixtures of Neon, Nitrogen, and Mercury Dichloride Vapor in the Blue-Green Spectral Interval

“…Discharge plasma that arises in the mixture of a mercury dichloride vapor with other gases is a working medium for exciplex sources of coherent and spontaneous radiation in the blue-green spectral interval with the wavelength = 557 nm at the maximum emission intensity [1][2][3][4][5][6][7][8][9][10][11][12]. Such sources can be used in scientific researches, photonics, biotechnology, medicine, for the manufacture of gas-discharge indicator panels, as well as for the effective light control over photosynthesis, plant growth and development, and phytocenosis [13][14][15][16][17].…”

Multihalide operation of mercury halide lasers

“…Mercury halide lasers have already proven to be efficient high-energy sources of blue-green-yellow radiation (Schimitschek and Celto 1978, McGeoch et a1 1983, Shay et al 1985, Kushner et al 1985, Burnham 1978, Kvasnik and King 1983, Sugii and Sasaki 1986, Bazhulin et al 1978, 1986a the laser action occurring on the B + X transition of the HgX (X = Cl, Br, I) radical. Oscillation has been obtained using electron beam excitation (Parks 1977), photodissociation of the parent HgX2 molecule (Schimitschek et al 1977, Bazhulin 1978, 1986a, avalanche discharge pumping (Schimitschek and Celto 1978, Shay et a1 1985, Kushner et a1 1985, Burnham 1978, Kvasnik and King 1983, Sugii and Sasaki 1986) and electron beam sustained discharge pumping (e.g. McGeoch et al 1983).…”
