Summary
The small signal gain and absorption coefficients of a high uniformity, X-ray preionized XeCl laser have been measured. Their time evolution and wavelength dependence have been simultaneously detected with high resolution. Two distinct estimates of the saturation intensity were obtained by means of a Rigrod-type analysis of the intracavity intensity and by using saturated gain measurements.
Riassunto
I coefficienti di guadagno a piccolo segnale e di assorbimento di un laser a eccimero XeCl, preionizzato a raggi X, sono stati misurati sia in funzione del tempo che della lunghezza d’onda. Inoltre sono stati ottenuti due valori per l’intensità di saturazione usando l’analisi di Rigrod sull’evoluzione dell’intensità fotonica all’interno della cavità e misure di guadagno in condizioni di saturazione.
Резюме
Измеряются усиление малых сигналов и коэффициенты поглощения рентгеновского, предионизонного XeCl лазера с высокой однородностью. С высоким разрешением одновременно определяются временная эволюция и зависимость от длины волны. Получаются две различные оценки интенсивности насьшения, используя анализ внутриполостной интенсивности и измерения усиления.
