Highly Efficient Pulsed-Operation Nd:Glass Quantron for a Large-Aperture Laser

The paper considers specifics of developing a highly efficient pulsed-operation Nd:Glass quantron that employs lamp pumping and may be used in a powerful large-aperture laser. We combined a 920 mm long gain element with a diameter of 45 mm and a part of a quantron designed to use standard 6...7 mm diameter lamps set up for pulsed operation, and compared spatial power distribution parameters of the resulting design with parameters of a quantron featuring INP-16/850 lamps. Experimental investigation results showed that the quantron under development should noticeably surpass its prototype in terms of the metrics considered, that is, energy efficiency and uniformity of population inversion distribution in the gain element
