In-situ monitoring of the vacuum chamber pressure during laser-induced oxide desorption on W surfaces provides a view on the desorption process. Sudden pressure variations suggest a change in the rate of desorption. During the desorption experiment, due to the incident pulsed UV laser light, photoelectrons are ejected from the sample surface. Evaluating the temporal variation of the measured charge shows a good agreement with the obtained pressure measurements. These results are attributed to the specific oxide structure on the W consisting of various tungsten oxides.
