A new instrument at the NOVA laser facility has been developed to measure absolute levels of scattered light at up to seven angles simultaneously from laser‐produced plasmas. The multiple‐angle time‐resolving spectrometer (MATRS) both temporally (t=120 ps) and spectrally (&lgr;=1 A˚) resolves light scattered from the plasma at or near the laser wavelength. MATRS has been used to study parametric instabilities in plasmas pertinent to laser fusion. Measurement of the angular dependence of the scattered light from these processes will provide a clear test of convective theory. This work was performed under the auspices of the U. S. Department of Energy by the Lawrence Livermore National Laboratory under Contract No. W‐7405‐ENG‐48.
