Editor’s choice Applied Physics A

The journal Applied Physics A has selected a publication from the EUV Generation and Imaging group led by Stefan Witte as this month’s Editor’s Choice. First author Tiago Pinto and his colleagues succeeded in controlling to a certain extent the deformation of tin droplets after they had been hit by a laser beam.

The researchers established the effect by controlling the polarization of the incident laser light. These results are of interest to anybody making or using EUV light sources because it may well be possible to use the technique to create tin droplet shapes that emit EUV light more efficiently. In this particular project the team did not look into this; they focused on being able to steer the deformation process.
