Efficient wide-aperture neodymium glass rod amplifiers

Amplifiers based on neodymium phosphate glass rods 60 — 100 mm in diameter are experimentally studied. The amplifiers are pumped by INP-16/250 tubular flash lamps placed in a universal pump cavity with a two-section mirror reflector. A compact high-voltage capacitive energy storage with a preionisation circuit was developed to supply the lamps.
