Seminars

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

Date: Jul 15, 2016
Time: 02:00 PM - 03:00 PM (Local Time Germany)
Speaker: Prof. Dr. Tashiki Tajima, Department of Physics & Astronomy, University of California, Irvine, USA
Room: Herbert Walther Lecture Hall
Host: 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. [more]

Prospects for Laser Cooling Hydrogen and Antihydrogen (Dr. D. Yost)

Date: Mar 15, 2016
Time: 02:00 PM - 04:00 PM (Local Time Germany)
Speaker: Dr. Dylan Yost, Department of Physics, Colorado State University, USA
Room: Herbert Walther Lecture Hall
Host: MPQ, Laser Spectroscopy Division

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

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

Date: Jan 11, 2016
Time: 03:30 PM - 05:00 PM (Local Time Germany)
Speaker: Prof. Dr. Federico Capasso, School of Engineering and Applied Sciences, Harvard University, Cambridge MA
Room: Herbert Walther Lecture Hall
Host: 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. [more]
