Intrapulse Impact Processes in Dense-Gas Femtosecond Laser Filamentation
Dmitri A. Romanov, Xiaohui Gao, Alexander L. Gaeta +1
The processes of energy gain and redistribution in a dense gas subject to an intense ultrashort laser pulse are investigated theoretically for the case of high-pressure argon. The…
Loss of Polarization in Collapsing Beams
Gauri Patwardhan, Xiaohui Gao, Amir Sagiv +5
We show theoretically and demonstrate experimentally that collapsing elliptically-polarized laser beams experience a nonlinear ellipse rotation that is highly sensitive to small fl…
Synchronization of coupled optical microresonators
Jae K. Jang, Alexander Klenner, Xingchen Ji +3
The phenomenon of synchronization occurs universally across the natural sciences and provides critical insight into the behavior of coupled nonlinear dynamical systems. It also off…
Gas-phase microresonator-based comb spectroscopy without an external pump laser
Mengjie Yu, Yoshitomo Okawachi, Chaitanya Joshi +3
We present a novel approach to realize microresonator-comb-based high resolution spectroscopy that combines a fiber-laser cavity with a microresonator. Although the spectral resolu…
Fully integrated ultra-low power Kerr comb generation
Brian Stern, Xingchen Ji, Yoshitomo Okawachi +2
Optical frequency combs are broadband sources that offer mutually-coherent, equidistant spectral lines with unprecedented precision in frequency and timing for an array of applicat…
Strong Nonlinear Coupling due to Induced Photon Interaction on a SiN Chip
Sven Ramelow, Alessandro Farsi, Zachary Vernon +6
Second-order optical processes lead to a host of applications in classical and quantum optics. With the enhancement of parametric interactions that arise due to light confinement,…
