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…
Entropy mode driven gas optics
P. Michel, A. Oudin, H. Rajesh +9
We propose a novel class of gaseous diffractive optical elements created by imprinting an entropy mode in a gas. Previous approaches to gaseous diffractive optics relied on the sim…
