Abstract

The single beam Asterix IV high power iodine laser ((lambda) equals 1.32 micrometers ) provides at present a maximum output energy of 2.1 kJ at a pulse length of 5 ns and an output power of 4 TW at 0.3 ns pulses. This laser is designed to deliver pulses with lengths ranging from 0.2 to 5 ns with a maximum power of 5 TW and an energy of up to 2 kJ. Asterix IV has been developed on the 10 years experience with the 1 TW Asterix III laser and with the support of a 1D and a 3D pulse propagation code. Special emphasis has been put on achieving a high overall system efficiency and laser beam intensity profile as homogeneous as possible. In this paper the measures for optimizing the laser performance and the results obtained will be described.
