A nanosecond light pulser suitable for spectroscopic studies and its emission characteristics are described.The discharge lamps mounted in the pulser generate sharp light pulses of the duration of 5 to 8 nanosecond, and can be fired as accurate as 0.1 nanosecond in syn-chronism with external trigger pulses.The unique discharge lamps having straight wire electrodes crossed each other with accurate gap separations are developed.<BR>Pulsed emission characteristics of hydrogen or deuterium filled lamps under various operating parameters such as gas pressure, electrode gap distance, supply voltage and discharge capacitance, are measured with a time-resolved spectrometer using the stroboscopic principle.With the deuterium lamps, the clear continum from 2000 to 5000Å are obtained during the entire discharge period.<BR>To demonstrate the performance of the pulser as the exitation source, a result of transient measurement of fluorescence radiation from 10<SUP>-3</SUP> mol deoxygenate solution of chrysene in cyclohexane is presented.
