Our Xenon Pulsers are used for Transient Absorption Spectroscopy systems. They generate a strong white light pulse that is shone upon a sample.
We keep receiving questions regarding the stability of such pulses. Here are two movies showing how those pulses behave in real life.
Video demonstration 1
Contrary to the comment in the video, the autoscaling of the plot was on and you can judge it from the motion of the thick grey horizontal line with indicates 0 V on the vertical scale.
So, all signal jiggling needs to be related to the position of that line. Since they jiggle the same, the jiggling is due to the autoscaling of the plot.
The movie has been recorded for the 5% pulse strength.
Video demonstration 2
Here is another movie with 20% pulse power at the width of 50 us (previous was 500 us). We had to narrow both monochromator slits from 500 um to 100 um and lower the PMT power supply voltage to the 200 V (bellow a sane level) not to have it saturated.
