Abstract

The effect of radiation losses in determining scaling laws of electron temperature on laser flux F φ is discussed for moderate Z plasmas created by lasers in the flux range 1011-1013 W/cm2. Temperature scaling slower and faster than φ49, observed by various authors, is explained by including radiation losses in a self-regulatory model. Results of experiments on carbon plasma produced by 1-GW, 5-nsec Nd: glass laser show temperature scaling φ0.25 and φ0.75, and are in good agreement with the predicted behavior.
