Large non-thermal contribution to picosecond strain pulse generation using the photo-induced phase transition in VO2

Ultrafast driving of vanadium dioxide can induce a large structural phase transition, which can be used to generate picosecond strain pulses. Here the authors show that the photo-induced phase transition can contribute 0.45% strain without causing undesirable heating.
