Odd-integer half-harmonic spectra from laser-produced plasmas have been reported since 1970. They have been clearly identified as related to parametric processes near n/sub c//4, most prominently the 2..omega../sub p/ decay instability. In this paper we present arguments for the exercise of greater caution in the use of the 3..omega../2 spectral splitting as a temperature diagnostic. We further discuss a model to explain the various features of the ..omega../2 spectra and we will show that one of its features is well suited as a temperature diagnostic. Furthermore, we will discuss fine structure observed in both the ..omega../2 and 3..omega../2 spectra which appears to be related to secondary decay processes near n/sub c//4.
