Hard X-ray Generation and Detection of Nanometer-Scale Localized Coherent Acoustic Wave Packets in SrTiO and KTaO
Yijing Huang, Peihao Sun, Samuel W. Teitelbaum +21
We demonstrate that the absorption of femtosecond x-ray pulses can excite quasi-spherical high-wavevector coherent acoustic phonon wavepackets using an all x-ray pump and probe sca…

Time-domain Brillouin Scattering as a Local Temperature Probe in Liquids
I. Chaban, H. D. Shin, C. Klieber +4
We present results of time-domain Brillouin scattering (TDBS) to determine the local temperature of liquids in contact to an optical transducer. TDBS is based on an ultrafast pump-…

Time-domain Brillouin scattering for the determination of laser-induced temperature gradients in liquids
I. Chaban, D. Shin, C. Klieber +4
We present an optical technique based on ultrafast photoacoustics to precisely determine the local temperature distribution profile in liquid samples in contact with a laser heated…
