    Exploring electron dynamics in solids

    A team of Prof. Ulf Kleineberg at the Chair ox Experimental Physics – Laserphysics at the Ludwig-Maximilians-Universität München is investigating ultrafast electron dynamics in solids by means of time resolved photoemission spectroscopy in the XUV spectral region. Utilizing intra-cavity generated attosecond pulse trains the scientists are able to measure with high flux at high photon energies and megahertz repetition rate.

    Preparing blood samples

    At the newly established bio lab Liudmila Voronina examines blood samples. With the help of these samples the team under the leadership of Dr. Mihaela Zigman aims to develop a method to detect cancer at an early stage by using broadband infrared spectroscopy. Further information on this can be found on the new website of the Centre for Advanced Laser Applications (CALA).

    A new generation of laser pulses

    <span class="proper name">Martin Gorjan</span> works on the development of the new <span class="proper name">PFS-pro_Lasersystem</span> in the <span class="proper name">Laboratory for Extreme Photonics </span>(<span class="proper name">LEX Photonics</span>). <span class="proper name">PFS-pro</span> is a high-power laser, which generates ultrashort and extremely intense light pulses. The pulses will be used in attosecond physics to explore the fastest processes in the microcosm as well as for laser-driven particle acceleration.

    High-repetition-rate picosecond pump laser

    Producing isolated attosecond extreme-<span class="abbr">UV</span> pulses via high harmonic generation requires high-energy fewcycle pulses preferably with kilohertz repetition rates for exploring hyperfast electronic phenomena. Ultrashort pulses in the range of a few femtoseconds at approximately kilohertz repetition rates have been demonstrated using a complex design consisting of an oscillator, a multipass chirped pulse amplifier, and an additional nonlinear compression stage. However, it has been difficult to extend these systems to the multimillijoule level. Optical parametric chirped pulse amplifiers (<span class="abbr">OPCPA</span>s) have emerged as a powerful alternative for creating broadband fewcycle pulses and are the only method by which high energy multimillijoule few-cycle coherent light pulses have been generated.The use of shorter pump pulses in the range of a few picoseconds eliminate the need for a large stretching and compressing ratio and allow stretching of the seed pulses by passing through a few-centimeters-long dispersive optical material and recompression by a highly efficient compressor made up a few chirped multilayer mirrors. Furthermore, the threshold intensity for optical damage of transparent materials increases for laser pulse durations decreasing below <span class="number">20</span> ps. As a consequence, exposing the nonlinear crystal to higher intensities allows the same optical parametric amplification (<span class="abbr">OPA</span>) gain to be attained with a shorter crystal and hence over a broader bandwidth.

  • Mechanism of the acceleration of electrons near silica nanospheres

    Mechanism of the acceleration of electrons near silica...

    Electrons (depicted as green particles) are released by the laser field (red wave). These electrons are first accelerated away from the particle surface and then driven back to it by the laser field. After an elastic collision with the surface, they are accelerated away again and reach very high kinetic energies. The figure shows three snapshots of the acceleration (from left to right): 1) the electrons are stopped and forced to return to the surface, 2) when reaching the surface, they elastically bounce right back 3) the electrons are accelerated away from the surface of the particle reaching high kinetic energies.

    New light for attosecond experiments

    The slender stainless-stell nozzles in a vacuum chamber of the <span class="proper name">AS4b</span> attosecond beamline extend like stalactites into the center of the experimental setup. From the right-hand edge of the photo the physicists focus invisible infrared light pulses lasting about <span class="number">3.5</span> femtoseconds exactly on the center of the left-hand gas nozzle, which emits neon gas whose atoms are exited by the infrared light pulses, thus giving them a reddish fluorescence. The right-hand gas nozzle, on the other hand, emits the argon, which emits a blue fluorescence, likewise due to the excitation caused by the infrared light. In this excitation process the rare-gas atoms produce light pulses both in the ultraviolet (<span class="abbr">UV</span> wavelength about <span class="number">250</span> nanometer) and in the extreme ultraviolet spectrum of the light (<span class="abbr">XUV, wavelength about <span class="number">8</span> nanometers).</span>
