Probing Optical Magnetic Dipole Transitions in Eu using Structured Light and Nanoscale Sample Engineering
Elizaveta Gangrskaia, Thomas Schachinger, Christoph Eisenmenger-Sittner +5
At optical frequencies, interactions of the electric field component of light with matter are dominating, whereas magnetic dipole transitions are inherently weak and challenging to…
Suppression of Kerr-Induced Satellites in Multi-Pulse CPA
Vinzenz Stummer, Edgar Kaksis, Audrius Pugžlys +1
Amplification of bursts of ultrashort pulses is very challenging when the intraburst repetition frequency reaches the THz range, corresponding to (sub)-ps intervals between consecu…
Fast Gain Dynamics in Interband Cascade Lasers
Florian Pilat, Andreas Windischhofer, Maximilian Beiser +8
Interband Cascade Lasers (ICL) have matured into a versatile technological platform in the mid-infrared spectral domain. To broaden their applicability even further, ongoing resear…
Bright Coherent Ultrahigh Harmonics in the keV X-Ray Regime from Mid-Infrared Femtosecond Lasers
Tenio Popmintchev, Ming-Chang Chen, Dimitar Popmintchev +17
High harmonic generation traditionally combines ~100 near-infrared laser photons, to generate bright, phase matched, extreme ultraviolet beams when the emission from many atoms add…
Analysis of High-Contrast All-Optical Dual Wavelength Switching in Asymmetric Dual-Core Fibers
Le Xuan The Tai, Mattia Longobucco, Nguyen Viet Hung +8
We systematically present experimental and theoretical results for the dual-wavelength switching of 1560 nm, 75 fs signal pulses (SPs) driven by 1030 nm, 270 fs control pulses (CPs…
Hyper Spectral Resolution Stimulated Raman Spectroscopy with Amplified fs Pulse Bursts
Hongtao Hu, Tobias Flöry, Vinzenz Stummer +5
We present a novel approach to achieve hyper spectral resolution, high sensitive detection, and high speed data acquisition Stimulated Raman Spectroscopy by employing amplified off…
