Extended Data Fig. 7: Absence of beam deflection effects.
From: Polarized phonons carry angular momentum in ultrafast demagnetization
a, Two time-delayed electron beams on the screen. b, Intensity changes in the reference pulse (black) and probe pulse (blue), showing a Debye–Waller effect in the probe beam only. c, Differences of the beam positions before and after laser excitation as a function of the pump–probe delay, converted to angle changes at the specimen. All changes remain below 5 µrad.
