Abstract:

The self-generated magnetic field produced when a pulsed Ndglass laser is focused onto a carbon foil target is measured for the first time using the Zeeman effect. Emission from the CV 1s2s3S sub 1-1s2p3 P sub 2 2270.9A was used for the measurement. At a laser irradiance of approx 5 X 10 to the 12th power Wcm2, the distribution to a ring pattern, which caused higher density gradients. A Faraday rotation measurement at approx 200 kG agreed with the Zeeman effect measurement. Opacity effects in the plasma enhanced the sensitivity of the Zeeman measurement. Author
