Performance of the ASTERIX III high power iodine laser
For more than 500 shots the 1 TW iodine laser Asterix III has demonstrated high reliability for light-plasma-interaction experiments. Improved laser parameters and new measurements of light pulse properties are reported.
The asterix III pulsed high-power iodine laser
A system description and first results of the Asterix III high-power iodine laser built at IPP Garching are given. This laser is designed to yield an output energy of 1 kJ in about 1 ns. Until now pulses with output energies up to 300 J and pulse lengths ranging from 1 to 3 ns have been obtained.
Pressure broadening of the atomic iodine 52P1/2–52P3/2 transition
Pressure‐broadening coefficients for the atomic iodine 52P1/2–52P3/2 transition have been measured for several buffer gases using a laser gain technique. The results in MHz/Torr are as follows: CO2, 7.4±0.7; N2, 6.2±0.8; He, 3.6±0.3; Ne, 4.3±0.4; Ar, 5.1±0.5; Kr, 4.4±0.4; and Xe, 3.0±0.3. These values are compared to those predicted by impact theory.
