    Description

    Vintage (early years 70'), pulsed xenon - filled, high energy, low repetition frequency, linear flashlamp to pump long Nd:glass or ruby laser rods, type XL 615/9/10, made by English Electric Valve (EEV, now E2V Technologies), UK. The linear design assures the best pump efficiency in an elliptical pumping chamber, ideal for a large laser rod oscillator or amplifier. Discharge dimensions: 9 mm dia. x 254 mm length, ideally should match the laser rod size. Good for rods of 8 mm - 14 mm dia. and 250 mm - 280 mm length. Total length (with electrodes): 323 mm (picture #1). Outer diameter:11 mm. The electrodes are polarized, the anode is the shiny one, with a red dotmark (picture #2), the cathode is the grey one, with a "granulated-surface" appearance (picture #3). New, never used, no original package. The following charging/discharge circuit data are for a similar size flashtube made by Verre et Quartz, France, due to the unavailability of the EEV flashlamp catalog of that time (see flashlamps-vq.com/CatalogueVQF.pdf). The closest such lamp for comparison is VQX R13P9. Although the technology of the seals between the electrodes and the fused silica envelope is different at EEV from Verre et Quartz, the operating characteristics can be considered similar, at least as a first approximation.
