摘要： A laser pumping method pumps a primary amount of energy into the near red satellite band of a metal vapor and noble gas mixture laser medium and a lesser amount of energy is pumped into a highly excited level to stimulate laser output. The medium is can be a Rb vapor and Xe gas mixture. The lesser amount of energy is pumped into the laser medium to populate an excited level that lies above the upper laser level and transfers atomic or molecular population to the upper laser level by a nonradiative process. In preferred embodiments, the intermediate level is within a few kT of the upper laser level and the primary amount of energy is a large majority of the total energy. A laser device includes metal vapor and noble gas mixture laser medium to populate an intermediate level near an upper laser level, and pumping a lesser amount of energy into a highly excited level to stimulate laser output. The medium can be an Rb vapor and Xe gas mixture in preferred embodiments. A primary energy pump pumps population in a near red satellite band. A second energy pump having substantially less energy than the primary energy pump pumps population to a highly excited level.

摘要： A speculum body is configured to attach to the otoscope. An array of radially situated microchannels is within the speculum body and extends to apertures in a distal end of the speculum body. A power electrode array is within the speculum body positioned with respect to the microchannels to excite plasma generation within the microchannels. An optically transparent central portion is in the body to permit viewing of an eardrum by a practitioner. A method of treatment of the middle ear and/or middle ear cavity incudes actuating plasma jets to extend into the ear canal from a speculum attached to the otoscope and continuing the plasma jet treatment for a period of time sufficient to inactivate or kill a bacterial biofilm in the middle ear and/or the middle ear cavity.

摘要： A method of forming a microplasma device places a curable polymer material between a mold having a negative volume impression of microcavities and/or microchannels and a substrate. The polymer is cured and then the mold is separated from the solid polymer. The method can form a microplasma device that includes a substrate and either or both of a microchannel or microcavity defined in a polymer layer supported by the substrate. Electrodes arranged with respect to the polymer material can excite plasma in a discharge medium contained in the microchannel or the microcavity or both. A flexible mold is preferably used to fabricate transparent polymer microcavities onto rigid substrates. A rigid mold is preferably used to fabricate transparent polymer microcavities onto flexible substrates. Having one of the mold and the substrate flexible and the other rigid aids in the separation of the mold from the cured polymer.
