Laser meets electrons! Van der Veen lab achieves overlapping laser beam inside electron microscope.

The DETEM team has managed to spatially overlap a fiber-coupled nanosecond laser beam (3 ns, 532 nm), focused to a spot of ~5 um, with the electron beam inside our environmental TEM at the MRL. This is an important milestone - first experiments are in reach! Congrats to the whole team!
