Autor: Ravensbergen, C., Corre, V., Soave, E., Kreyer, M., Tzanova, S., Kirilov, E., Grimm, R.

Publikováno v: Phys. Rev. Lett. 120, 223001 (2018)

We report a measurement of the dynamical polarizability of dysprosium atoms in their electronic ground state at the optical wavelength of 1064 nm, which is of particular interest for laser trapping experiments. Our method is based on collective oscil

Tapered amplifier laser with frequency-shifted feedback

Autor: Bayerle, A., Tzanova, S., Vlaar, P., Pasquiou, B., Schreck, F.

Publikováno v: SciPost Phys. 1, 002 (2016)

We present a frequency-shifted feedback (FSF) laser based on a tapered amplifier. The laser operates as a coherent broadband source with up to 370GHz spectral width and 2.3us coherence time. If the FSF laser is seeded by a continuous-wave laser a fre

Report

Evaluation of the thermal and hydraulic performances of a very thin sintered copper flat heat pipe for 3D microsystem packages

Autor: Tzanova, S., Kamenova, L., Avenas, Y., Schaeffer, Ch.

Publikováno v: Dans Symposium on Design, Test, Integration and Packaging of MEMS/MOEMS - DTIP 2007, Stresa, lago Maggiore : Italie (2007)

The reported research work presents numerical studies validated by experimental results of a flat micro heat pipe with sintered copper wick structure. The objectives of this project are to produce and demonstrate the efficiency of the passive cooling
