The infrastructure operates several laser systems serving a diverse field of applications ranging from attosecond laser physics to laser particle acceleration. Examples of the extremes are an all-diode pumped 250 TW laser providing 25 J of pulse energy with 100 fs pulse width, a 17 fs 200 TW Ti:sapphire-laser and a kilohertz phase-stabilized few-cycle laser. The institute has equally strong programs in laser development and applications for high intensity laser-matter interactions. For instance, HIJ is engaged in the development of diode pumped near- and mid-infrared high energy ultra-short pulse laser systems as well as high average power lasers with carrier envelope phase control. Application development ranges from particle acceleration (electrons, ions), plasma diagnostics with temporal resolution (shadography, holography, spectroscopy, reflectometry) to the generation of secondary sources (high harmonics, XUV, X-rays, THz) and their application for imaging technologies like XUV coherence tomography or ptychography.

Excellence:

HIJ has a long lasting experience in diode-pumped high-power laser development, relativistic optics, few-cycle plasma probing, CE-phase measurement, nanoscale XUV imaging and high intensity lasermatter interaction simulation. With more than seven independent high-power laser laboratories a foundation covering many different applications is readily available. Additionally, there are a lot of sophisticated measurement techniques for carrier envelope stabilized laser applications or plasma diagnostics ranging from spectroscopy to dosimetry and imaging at the institute.
