Seed source for plasma compression in the long wavelength infrared
Daniel F. Gordon, Patrick Grugan, Rotem Kupfer +5
Two color laser pulses are used to form an air plasma and generate broadband infrared radiation suitable as a seed for backward Raman amplification of CO2 laser pulses. Broadband r…
Vortex dynamics and applications to gaseous optical elements
D. Kaganovich, B. Hafizi, L. A. Johnson +1
Experimental studies of the optical properties of compressible, viscous and rapidly-rotating gas flows (vortices) are presented. Gas vortices can function as optical elements such…
Lensing properties of rotational gas flow
D. Kaganovich, L. A. Johnson, D. F. Gordon +2
A negative lens comprised of a gas in steady axisymmetric flow is demonstrated experimentally and analyzed. The lens has potential applications in high-intensity laser optics and p…
Backward Raman Amplification in the Long-wavelength Infrared
L. A. Johnson, D. F. Gordon, J. P. Palastro +1
The wealth of work in backward Raman amplification in plasma has focused on the extreme intensity limit, however backward Raman amplification may also provide an effective and prac…
Synchrotron radiation from a curved plasma channel laser wakefield accelerator
J. P. Palastro, D. Kaganovich, B. Hafizi +5
A laser pulse guided in a curved plasma channel can excite wakefields that steer electrons along an arched trajectory. As the electrons are accelerated along the curved channel, th…
Two-photon vibrational excitation of air by long-wave infrared laser pulses
J. P. Palastro, J. Penano, L. A. Johnson +3
Ultrashort long-wave infrared (LWIR) laser pulses can resonantly excite vibrations in N2 and O2 through a two-photon transition. The absorptive, vibrational component of the ultraf…
