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

    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!
