Paper Abstract

The Chemical Oxygen Iodine Laser (COIL) is an attractive candidate for easy power scaling at short wavelengths. High specific power output from supersonic operation leads to compact devices. The German Aerospace Research Establishment (DLR) has recently completed construction and assembly of a multikilowatt supersonic COIL and started experimental investigations at its Lampoldshausen rocket test site. The excited oxygen is produced by a rotating disk generator, provided by the Phillips Laboratory, Albuquerque, NM. Currently the laser is operated without a cold trap. After the injection of the iodine, the laser gas is expanded to an isotropical Mach number of 1.8 by a multi-element grid nozzle. At present, laser power is extracted with a single pass stable resonator located immediately after the nozzle exit plane. Pressure is recovered by a supersonic diffusor and a 3-stable pumping system.
