    摘要: A simple, reliable, easy to use method for calculating bandwidth data of very narrow band laser beams based on bandwidth data obtained with a spectrometer in circumstances where the laser bandwidths are not large compared to the slit function of the spectrometer. The slit function of the spectrometer is determined. Spectral data of the laser beam is measured with the spectrometer to produce a measured laser beam spectrum which represents a convolution of the laser beam spectrum and the spectrometer slit function. This measured laser spectrum is then mathematically convolved with the slit function of the spectrometer to produce a doubly convolved spectrum. Bandwidth values representing true laser bandwidths are determined from measured laser spectrum and the doubly convolved spectrum. Preferably the true laser bandwidths are calculated by determining the difference between “twice a measured laser bandwidth” and a corresponding “doubly convolved bandwidth”. This method provides an excellent estimate of the true laser bandwidth because “twice the measured laser bandwidth” represents two laser bandwidths and two spectrometer slit function bandwidths and the “doubly convolved bandwidth” represents one laser bandwidth and two spectrometer slit function bandwidths. Thus, the difference is a representation of the true laser bandwidth. In a preferred embodiment the bandwidth parameters measured are the full width half-maximum bandwidth and the 95% integral bandwidth.

    摘要: A tangential fan, configured to recirculate a lasing gas mixture, has blade members, which are twisted in a substantially helical fashion about the rotation axis of the fan. The circumferential number of blade members can be constant variable between the end flanges. The circumferential position of blade members can shift monotonically or reversibly between the two ends. A tangential fan in accordance with the invention can be made using a conventional method of brazing together individually stamped and formed blade members and hub members. Finishing processes typically include post-machining, electropolishing, and electroless nickel coating.

    摘要: A tangential fan for recirculating a lasing gas mixture has blade members, which vary in circumferential position stepwise from end to end. The number of blade members can be constant or variable between ends. The circumferential position of blade members can shift monotonically or reversibly between ends. Blade members are stiffened by one or more transverse annular hub members. A method of forming a tangential fan involves forming monolithic structures by casting or by machining from a solid block. Two or more monolithic structures can be joined together, typically by electron-beam welding. Casting, welding, and machining processes introduce no additional contaminants. Tangential fans produced have mechanical rigidity, accurate tolerances, and low contaminant concentrations. Methods provided by the invention facilitate forming of blade members into an air foil shape. Finishing processes typically include post-machining, electropolishing, and electroless nickel coating.
