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
Modelocking and femtosecond pulse generation in chip-based frequency combs.
Kasturi Saha,Yoshitomo Okawachi,Bonggu Shim,Jacob S. Levy,Reza Salem,Adrea R. Johnson,Mark A. Foster,Michael R. E. Lamont,Michal Lipson,Alexander L. Gaeta +9 more
TL;DR: The calculations show that pulse generation in this system is consistent with soliton modelocking, and such parametric devices offer the potential of producing ultra-short laser pulses from the visible to mid-infrared regime at repetition rates from GHz to THz.
Journal ArticleDOI
Ultraviolet surprise: Efficient soft x-ray high-harmonic generation in multiply ionized plasmas
Dimitar Popmintchev,Carlos Hernandez-Garcia,Carlos Hernandez-Garcia,Franklin Dollar,Christopher A. Mancuso,Jose A. Pérez-Hernández,Ming-Chang Chen,Amelia Hankla,Xiaohui Gao,Bonggu Shim,Alexander L. Gaeta,Maryam Tarazkar,Dmitri Romanov,Robert J. Levis,Jim Gaffney,Mark Foord,Stephen B. Libby,Agnieszka Jaron-Becker,Andreas Becker,Luis Plaja,Margaret M. Murnane,Henry C. Kapteyn,Tenio Popmintchev +22 more
TL;DR: Surprisingly, the high ultraviolet refractive indices of both neutral atoms and ions enabled effective phase matching, even in a multiply ionized plasma, which could presage a more generally efficient means of creating x-ray pulses for fundamental dynamics studies as well as technological applications.
Journal ArticleDOI
Strong optical nonlinearity of CVD-grown MoS 2 monolayer as probed by wavelength-dependent second-harmonic generation

Journal ArticleDOI
Three-octave-spanning supercontinuum generation and sub-two-cycle self-compression of mid-infrared filaments in dielectrics.
Houkun Liang,Peter Krogen,Ross Grynko,Ondrej Novak,Chun-Lin Chang,Gregory J. Stein,Darshana L. Weerawarne,Bonggu Shim,Franz X. Kärtner,Kyung-Han Hong +9 more
TL;DR: A supercontinuum is demonstrated that spans more than three octaves from ZnS in the normal GVD regime and self-compression of the mid-IR pulse to sub-two-cycle duration in CaF2 in the anomalousGVD regime is demonstrated.
