The accuracy that can be achieved in single-pulse pump-probe Laue experiments is discussed. It is shown that with careful tuning of the experimental conditions a reproducibility of the intensity ratios of equivalent intensities obtained in different measurements of 3-4% can be achieved. The single-pulse experiments maximize the time resolution that can be achieved and, unlike stroboscopic techniques in which the pump-probe cycle is rapidly repeated, minimize the temperature increase due to the laser exposure of the sample.
文中讨论了在单脉冲泵浦探测劳埃实验中可以达到的精度。结果表明,通过仔细调整实验条件,可以实现不同测量中获得的等效强度的强度比的可重复性,精度为 3-4%。单脉冲实验最大限度地提高了可以达到的时间分辨率,并且与快速重复泵浦探测循环的频闪技术不同,它可以最小化由于激光照射样品而导致的温度升高。
