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…
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…
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…
Photochemically-induced acousto-optics in gases
Pierre Michel, Livia Lancia, Albertine Oudin +6
Acousto-optics consists of launching acoustic waves in a medium (usually a crystal) in order to modulate its refractive index and create a tunable optical grating. In this article,…
