Observation of extremely efficient terahertz generation from mid-infrared two-color laser filaments
Anastasios D. Koulouklidis,Claudia Gollner,Valentina Shumakova,Vladimir Yu. Fedorov,Vladimir Yu. Fedorov,Audrius Pugžlys,Andrius Baltuška,Stelios Tzortzakis,Stelios Tzortzakis,Stelios Tzortzakis +9 more
TL;DR: Efficient sub-cycle THz pulse generation by using two-color midinfrared femtosecond laser filaments in ambient air using affordable table-top laser systems is experimentally demonstrated.
Journal ArticleDOI
Hydrogen-Bonded Organic Semiconductor Micro- And Nanocrystals: From Colloidal Syntheses to (Opto-)Electronic Devices
Mykhailo Sytnyk,Eric Daniel Głowacki,Sergii Yakunin,Gundula Voss,Wolfgang Schöfberger,Dominik Kriegner,Julian Stangl,Rinaldo Trotta,Claudia Gollner,Sajjad Tollabimazraehno,Giuseppe Romanazzi,Zeynep Bozkurt,Marek Havlicek,Niyazi Serdar Sariciftci,Wolfgang Heiss +14 more
TL;DR: The semiconducting nanocrystals described here offer a cheap, nontoxic, and environmentally friendly alternative to inorganic nanocry crystals as well as a new paradigm for obtaining organic semiconductor materials from commercial colorants.
Journal ArticleDOI
Random Lasing with Systematic Threshold Behavior in Films of CdSe/CdS Core/Thick-Shell Colloidal Quantum Dots
Claudia Gollner,Johannes Ziegler,Loredana Protesescu,Loredana Protesescu,Dmitry N. Dirin,Dmitry N. Dirin,Rainer T. Lechner,Gerhard Fritz-Popovski,Mykhailo Sytnyk,Sergii Yakunin,Sergii Yakunin,Stefan Rotter,Amir Abbas Yousefi Amin,Cynthia Vidal,Calin Hrelescu,Thomas A. Klar,Maksym V. Kovalenko,Maksym V. Kovalenko,Wolfgang Heiss +18 more
TL;DR: Random lasing at room temperature in films of CdSe/CdS CQDs with different core/shell band alignments and extra thick shells is reported, finding systematic dependencies of the laser thresholds on morphology and laser spot size.
Journal ArticleDOI
Laser wakefield acceleration with mid-IR laser pulses
Daniel Woodbury,Linus Feder,Valentina Shumakova,Claudia Gollner,Robert Schwartz,Bo Miao,Fatholah Salehi,Anastasia Korolov,Audrius Pugžlys,Andrius Baltuška,Howard Milchberg +10 more
TL;DR: These are the first results of laser plasma wakefield acceleration driven by ultrashort mid-infrared (IR) laser pulses, which enable near- and above-critical density interactions with moderate-density gas jets.
Journal ArticleDOI
Filamentation of mid-IR pulses in ambient air in the vicinity of molecular resonances
Valentina Shumakova,Skirmantas Alisauskas,Pavel Malevich,Claudia Gollner,Andrius Baltuška,Daniil Kartashov,Aleksei M. Zheltikov,Aleksandr V. Mitrofanov,A. A. Voronin,D. A. Sidorov-Biryukov,Audrius Pugžlys +10 more
TL;DR: Properties of filaments ignited by multi-millijoule, 90 fs mid-infrared pulses centered at 3.9 μm are examined experimentally by monitoring plasma density, losses, spectral dynamics and beam profile evolution at different focusing strengths.
