Efficient second-harmonic generation of a high-energy, femtosecond laser pulse in a lithium triborate (LBO) crystal
C. Aparajit, Kamalesh Jana, Amit D. Lad +3
We demonstrate the highest efficiency (80%) second harmonic generation (SHG) of Joule level, 27 femtosecond, high contrast pulses in a type-I lithium triborate (LBO) crystal.…
Post-compression of picosecond pulses into the few-cycle regime
Prannay Balla, Ammar Bin Wahid, Ivan Sytcevich +18
In this work, we demonstrate post-compression of 1.2 picosecond laser pulses to 13 fs via gas-based multi-pass spectral broadening. Our results yield a single-stage compression fac…
Ab-initio calculations of the linear and nonlinear susceptibilities of N, O, and air in the mid-infrared
Jeffrey M. Brown, Arnaud Couairon, Mette B. Gaarde
We present first-principles calculations of the linear and nonlinear susceptibilities of N, O, and air in the mid-infrared wavelength regime, from m. We extract th…
Ultrafast supercontinuum generation in bulk condensed media (Invited Review)
Audrius Dubietis, Gintaras Tamošauskas, Rosvaldas Šuminas +2
Nonlinear propagation of intense femtosecond laser pulses in bulk transparent media leads to a specific propagation regime, termed femtosecond filamentation, which in turn produces…
Underwater acoustic wave generation by filamentation of terawatt ultrashort laser pulses
Vytautas Jukna, Amelie Jarnac, Carles Milián +9
Acoustic signals generated by filamentation of ultrashort TW laser pulses in water are characterized experimentally. Measurements reveal a strong influence of input pulse duration…
Scale-invariant nonlinear optics in gases
C. M. Heyl, H. Coudert-Alteirac, M. Miranda +8
Nonlinear optical methods are becoming ubiquitous in many areas of modern photonics. They are, however, often limited to a certain range of input parameters, such as pulse energy a…
