Dispersive Properties of Plasma Diffraction Gratings: Towards Plasma-Based Laser Pulse Compression
Victor M. Perez-Ramirez, Michelle M. Wang, Ke Ou +10
The standard architecture for a high-peak-power femtosecond laser is chirped pulse amplification using diffraction gratings for compression; the damage threshold of the compression…
Intense tunable terahertz radiation from phase-matched difference frequency generation in strongly magnetized plasmas
Sida Cao, Matthew R. Edwards
High-energy terahertz pulses are challenging to produce due to the low conversion efficiency and limited optical damage threshold of nonlinear crystals. Here, we describe the high-…
Near-Unity-Efficiency Gas Gratings for Ultraviolet, Visible, and Infrared High-Power Lasers
Ke Ou, Harsha Rajesh, Sida Cao +13
Interfering deep ultraviolet (DUV) lasers can induce substantial density modulations in an ozone-doped gas flow via photochemical reactions, creating volume diffraction gratings. T…
Phase-Matched Harmonic Generation in Strongly Magnetized Plasma
S. Cao, M. R. Edwards
Harmonic generation in underdense spatially homogeneous plasma is generally expected to be inefficient: in an unmagnetized uniform plasma the fundamental and its harmonics cannot b…
