Experimental Scaling of Diffraction Efficiency in Laser-Induced Plasma Gratings

M. M. Wang, V. M. Perez-Ramirez, N. M. Fasano +8

We demonstrate efficient diffraction of intense ultrashort laser pulses using optical-field-ionization-induced plasma-neutral gratings formed by spatially structured ionization of…

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…

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…

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…

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…
