“…The main feature displayed by the spectra is bleaching (blue shift) in the intrinsic absorption region. Such a behaviour in CdS at room temperature was earlier observed in experiments with ns laser pulses [3]. The shapes of spectral curves in the region of transparency are formed by the Fabry-Perot interferences.…”

Optical spectra above the Mott transition of excitons are calculated from the inhomogeneous integral equation For the polarization function including self-energy, screening, and band filling. Taking CdS parameters and adjusted values OF the electron-hole temperature and density, good agreement is achieved with the results of transmission measurements made at room temperature on a thin CdS crystal using two-beam excite-and-probe technique with 5 ps time resolution.Optische Spektren oberhalb des Mott-Ubergangs der Exzitonen werden mit Hilfe der inhomogenen Integralgleichung fur die Polarisationsfunktion berechnet, die Selbstenergie, Abschirmung und Bandfullung einschlieBt. Unter Verwendung der CdS-Parameter und geeigneter Werte der Temperatur und Dichte der Elektron-Loch-Paare wird eine gute obereinstimmung mit den Ergebnissen der Transmissionsmessungen erreicht, die bei Zimmertemperatur an einem dunnen CdS-Kristall nach der Zweistrahlmethode mit Zeitauflosung von 5 ps gemacht werden.

Results of laser pulse transmission measurements are presented. Introducing a variable optical delay between exciting and probing pulse the relaxation behaviour of induced optical nonlinearities in the spectral region around the A,,I-exciton resonance is investigated. Optical bistability reported earlier is supported. Crystal lattice heating and nonstationarity due to long-living extrinsic effects are observed, too, but are of minor importance.Es werden die Resultate von Laserimpuls-Transmissionsmessungen vorgestellt. Mit Hilfe einer variablen optischen Verzogerung zwischen anregendem und testendem Lichtimpuls wird das Relaxationsverhalten anregungsinduzierter optischer Nichtlinearitaten im Spektralgebiet der A,,I-Exzitonenresonanz untersucht. Eine friiher gegebene Interpretation im Sinne einer optischen Bistabilitat wird bestatigt. Die Kristallgitteraufheizung und Nichtstationaritat infolge langlebiger extrinsischer Effekte wird zwar ebenfalls beobachtet, ist jedoch von untergeordneter Bedeutung.
