Bright Coherent Ultrahigh Harmonics in the keV X-ray Regime from Mid-Infrared Femtosecond Lasers
Tenio Popmintchev,Ming-Chang Chen,Dimitar Popmintchev,Paul Arpin,Susannah Brown,Skirmantas Alisauskas,Giedrius Andriukaitis,Tadas Balciunas,Oliver D. Mücke,Audrius Pugzlys,Andrius Baltuška,Bonggu Shim,Samuel E. Schrauth,Alexander L. Gaeta,Carlos Hernandez-Garcia,Luis Plaja,Andreas Becker,Agnieszka Jaron-Becker,Margaret M. Murnane,Henry C. Kapteyn +19 more
TL;DR: By guiding a mid-infrared femtosecond laser in a high-pressure gas, ultrahigh harmonics can be generated that emerge as a bright supercontinuum that spans the entire electromagnetic spectrum from the ultraviolet to more than 1.6 kilo–electron volts, allowing, in principle, the generation of pulses as short as 2.5 attoseconds.
Journal ArticleDOI
2D IR spectroscopy at 100 kHz utilizing a Mid-IR OPCPA laser source
TL;DR: A 100 kHz 2D IR spectrometer using a ytterbium all normal dispersion fiber oscillator as a common source for the pump and seed beams of a MgO:PPLN OPCPA allowing for data collection at 100 kHz.
Proceedings ArticleDOI
Ultrahigh-efficiency high harmonic generation driven by UV lasers
Dimitar Popmintchev,Ming-Chang Chen,Carlos Hernandez-Garcia,Jose A. Pérez-Hernández,Jonathas Sequeira,Susannah Brown,Franklin Dollar,Patrik Grytchtol,Barry C. Walker,Luis Plaja,Margaret M. Murnane,Henry C. Kapteyn,Tenio Popmintchev +12 more
TL;DR: In this article, the authors demonstrate bright high harmonic generation driven by UV lasers with ultra-high conversion efficiency approaching 10−3 and ultra-narrow single-harmonic bandwidth of ∼0.2%.
Proceedings ArticleDOI
High repetition rate, mJ-level, mid-IR OPCPA system
Michael Gerrity,Susannah Brown,Tenio Popmintchev,Margaret M. Murnane,Henry C. Kapteyn,Sterling Backus +5 more
TL;DR: In this article, a kHz repetition-rate mid-IR laser system based on OPCPA was proposed, optimized for soft x-ray high harmonic generation, with bandwidth compressible to <100fs.
Proceedings ArticleDOI
High power, 60MHz, cryogenically cooled, mode-locked, Yb:YAG oscillator
Michael Gerrity,Susannah Brown,Tenio Popmintchev,Ming-Chang Chen,Stefan Witte,Margaret M. Murnane,Henry C. Kapteyn,S. Backus +7 more
TL;DR: In this article, a 60MHz, cryogenically cooled, mode-locked Yb:YAG oscillator with up to 12W average output power was demonstrated, achieved via a SESAM, an intracavity SHG crystal, and an iris near focus for spatial mode filtering.
