Single-cycled laser acceleration of ions and “TeV on a chip” acceleration (Prof. T. Tajima)

Datum: 15.07.2016
Uhrzeit: 14:00 - 15:00
Vortragende(r): Prof. Dr. Tashiki Tajima, Department of Physics & Astronomy, University of California, Irvine, USA
Raum: Herbert Walther Lecture Hall
Gastgeber: MPQ, Laser Spectroscopy Division

In order to increase the electron energy gain by the laser wakefield acceleration (LWFA), three ways are known. The first way is to multi-stage the LWFA beyond the dephasing length. The second method is to decrease the plasma density so that the dephasing length is increased. [mehr]

In this talk, I will discuss our progress in the development of a two-photon laser-cooling scheme for hydrogen. [mehr]

Flat optics: structuring light with metasurfaces (Prof. F. Capasso)

Datum: 11.01.2016
Uhrzeit: 15:30 - 17:00
Vortragende(r): Prof. Dr. Federico Capasso, School of Engineering and Applied Sciences, Harvard University, Cambridge MA
Raum: Herbert Walther Lecture Hall
Gastgeber: MPQ, Laser Spectroscopy Division

Patterning surfaces with subwavelength spaced metallo-dielectric features (metasurfaces) allows one to generate complex 3D and 2D wavefronts by locally controlling the amplitude, phase and polarization of the scattered light. [mehr]
