Set of 2 high-energy, pulsed flashlamps to pump Nd:glass/ruby laser rods, new

Description

The set consists of 2 (two) pulsed xenon - filled, high energy, linear flashlamp to pump Nd:glass or ruby laser rods, type IFP 800, made in Russian Federation. The linear design assures the best pump efficiency in an elliptical pumping chamber, ideal for a large laser rod oscillator or amplifier. Discharge dimensions: 8 mm dia. x 80 mm length, ideally should match the laser rod size. Good for rods of 6 mm - 10 mm dia. and 75 mm - 90 mm length. Outside diameter 10 mm, total flashtube length (with electrodes) 300 mm.
Anode end marked on the tube with + sign, cathode at the end with letters OTK.
New, never used, vintage (years 70'), no original box (see the label from an original box, last picture). Maximum pump energy E
