XUV diagnostic equipment was designed and utilized on the OMEGA target chamber at the University of Rochester to study high atomic number plasma generation by two-wavelength laser excitation. Spectral data were collected from silver tracer dot targets irradiated with 1/3 TW of 0.35-..mu..m laser light of the multiple-beam OMEGA laser and the single synchronized 1.06-..mu..m beam of the GDL laser for generating energetic electrons. XUV spectral data in the 30--300-A region were obtained with both a 3-m grazing incidence spectrograph and a compact 1-m grazing incidence spectrograph designed for reentrant mounting in the OMEGA chamber. High-resolution x-ray spectra were acquired in the 3.6--4.2-A region with a dual, flat-diffraction crystal spectrograph. A low-resolution x-ray spectrum of silver was recorded with a curved mica spectrograph. Some x-ray spectral lines appeared only when both OMEGA and GDL beams were used. These were identified as 2p--3s,3d transitions in F-like Ag XXXIX. F-, Na-, and Mg-like lines were found in the grazing incidence spectra, with F-like lines appearing only with 1.06-..mu..m irradiation.
