Book Description
Long-wavelength, short-duration laser pulses are desirable for plasma wakefield particle acceleration and plasma waveguiding. The first picosecond terawatt CO2 laser is under development to test laser-driven electron acceleration schemes.

Book Description
A table-top 20-GW 50-ps CO2 laser system is under operation at the Brookhaven Accelerator Test Facility. We compare laser performance with model predictions. Extrapolations suggest the possibility of compact terawatt CO2 laser systems suitable as laser accelerator drivers and for other strong-field applications. Latest progress on an Inverse Cherenkov Laser Accelerator experiment is reported.

Book Description
Extended cylindrical plasma channels produced under gas breakdown by axicon-focused laser beams may be used as optical waveguides in laser-driven electron accelerators. Plasma channeling of the laser beams will help to maintain a high acceleration gradient over many Rayleigh lengths. In addition, the rarefied gas density channel produced after the optical gas breakdown, and followed by a plasma column expansion, reduces multiple scattering of the electron beam. A high-power picosecond C02laser operational at the ATF and being further upgraded to the 1 TW level is considered as the source for a plasma channel formation and as the laser accelerator driver. We show how various laser accelerator schemes including beat wave, wake field, and Inverse Cherenkov accelerator benefit from using a channeled short-pulse C02laser as a driver.

Book Description
Over the last two decades, BNL's ATF has pioneered the use of high-peak power CO2 lasers for research in advanced accelerators and radiation sources. In addition, our recent developments in ion acceleration, Compton scattering, and IFELs have further underscored the benefits from expanding the landscape of strong-field laser interactions deeper into the mid-infrared (MIR) range of wavelengths. This extension validates our ongoing efforts in advancing CO2 laser technology, which we report here. Our next-generation, multi-terawatt, femtosecond CO2 laser will open new opportunities for studying ultra-relativistic laser interactions with plasma in the MIR spectral domain, including new regimes in the particle acceleration of ions and electrons.

Book Description
Short-pulse, high-power C02 lasers open new prospects for development of high-gradient laser-driven electron accelerators. The advantages of [lambda]=10 [mu]m CO2 laser radiation over the more widely exploited solid state lasers with [lambda]≈1 [mu]m are based on a [lambda]2-proportional ponderomotive potential, [lambda]-proportional phase slippage distance, and %-proportional scaling of the laser accelerator structures. We show how a picosecond terawatt C02 laser that is under construction at the Brookhaven Accelerator Test Facility may benefit the ATFs experimental program of testing far-field, near-field, and plasma accelerator schemes.
