Interpretation of an optically thick resonance line emitted from laser‐heated spherical plasmas

摘要

An interpretation is provided for the radiation emitted by optically thick resonance lines produced from laser‐heated plasmas. The profiles and total intensities are shown to be sensitive to the spatial profiles of the laser energy deposition. Results are presented for the helium‐like resonance line of Al XII. It is also shown that Holstein’s photon escape approximation badly underestimates the emitted line radiation.
