Autor: Ghawas M., Freysz V., Pontagnier L., Cormier E., Santarelli G., Freysz E.

Publikováno v: EPJ Web of Conferences, Vol 307, p 02027 (2024)

We demonstrate a 16 GHz repetition rate fiber-based optical parametric oscillator, pumped by an electro-optical comb tunable around 1.03 µm, delivering picosecond and wavelength tunable signal and idler pulses. Build-up and relaxation dynamics of th

High spin ↔ low spin ultrafast excitation and relaxation of an isolated iron(II) complex.

Autor: Létard J.F., Mauriac C., Tondusson M., Jonusauskas G., Tribollet J., Galle G., Freysz E.

Publikováno v: EPJ Web of Conferences, Vol 41, p 05010 (2013)

Picosecond and femtosecond time resolved pump-probe experiments make it possible to study both the low spin (LS) to high spin (HS) and high spin to low spin excitation and relaxation processes in the same isolated iron(II) complex. We demonstrate tha

Direct observation of low frequency confined acoustic phonons in silver nanoparticles: Terahertz time domain spectroscopy

Autor: Kumar, Sunil, Kamaraju, N., Karthikeyan, B., Tondusson, M., Freysz, E., Sood, A. K.

Publikováno v: J. Chem. Phys. 133, 014502 (2010)

Terahertz time domain spectroscopy has been used to study low frequency confined acoustic phonons of silver nanoparticles embedded in poly(vinyl alcohol) matrix in the spectral range of 0.1 to 2.5 THz. The real and imaginary parts of the dielectric f
