Gas Beam Dump and Power Meter for High Energy Lasers
Harsha Rajesh, Sida Cao, Ke Ou +3
Gaseous optics exhibit substantially higher laser-induced-damage thresholds than solid materials, enabling high-intensity operation without permanent degradation. In this Letter, w…
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…
Flying focus with arbitrary directionality for spatiotemporal control of laser pulses
Sida Cao, Devdigvijay Singh, Lavonne S. Mack +2
Flying focus techniques produce laser pulses whose focal points travel at arbitrary, controllable velocities. While this flexibility can enhance a broad range of laser-based applic…
Focusing Terawatt-Scale Lasers Using Holographic Gaseous Lenses
Devdigvijay Singh, Ke Ou, Sida Cao +13
The capabilities of the world's highest energy and peak-power pulsed lasers are limited by optical damage, and further advances in high-intensity laser science will require optics…
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…
Electron penetration heating in turbulent magnetic loops driven by nonrelativistic laser-plasma interaction
Zheng Gong, Sida Cao, Caleb Redshaw +1
Using particle-in-cell simulations to study nonrelativistic laser pulse propagation in a under-critical plasma, we identify a novel mechanism that occurs during the growth of turbu…
High-energy transient gas pinholes via saturated absorption
Ke Ou, Victor M. Perez-Ramirez, Sida Cao +6
This letter presents a spatial filter based on saturated absorption in gas as a replacement for the solid pinhole in a lens-pinhole-lens filtering system. We show that an ultraviol…
Laser wakefield acceleration of ions with a transverse flying focus
Zheng Gong, Sida Cao, John P. Palastro +1
The extreme electric fields created in high-intensity laser-plasma interactions could generate energetic ions far more compactly than traditional accelerators. Despite this promise…
