| Zusammenfassung: | This paper presents results of our study of the performance of a Potassium DPAL operating in pulsed mode with pulses up to 5 msec long at different pulse energies and cell temperatures. The experiments showed the DPAL efficiency degradation in time with a characteristic time in the range from 0.5 msec to 4.5 msec. The recorded spectrum of the side fluorescence indicates that multi-photon excitation, energy pooling collisions and ionization may be strong candidates for explaining the observed performance degradation.
