Design of a kJ-class HiLASE laser as a driver for inertial fusion energy
نویسندگان
چکیده
We present the results of performance modeling of a diode-pumped solid-state HiLASE laser designed for use in inertial fusion energy power plants. The main amplifier concept is based on a He-gas-cooled multi-slab architecture similar to that employed in Mercury laser system. Our modeling quantifies the reduction of thermally induced phase aberrations and average depolarization in Yb3+:YAG slabs by a combination of helium cryogenic cooling and properly designed (doping/width) cladding materials.

Inverse Braking Radiation and Resonance Absorption in Corona Plasmas of Inertial Confinement Fusion
Abstract: In this paper, combining the Maxwell equations with the electron balanceequation, we obtain the inverse braking radiation absorption coefficient in a laser fusioncorona plasma. For a fixed plasma temperature, variations of the absorption coefficientversus the penetration depth into the plasma are illustrated numerically for differentvalues of laser wavelength. ...
متن کاملIF/P7-8 “GENBU”-Laser Development with Cryogenic Yb:YAG Ceramic for Fusion Energy Reactor Driver
A new diode-pumped laser fusion driver has been conceptually designed. The output power is 1.2 MJ and 0.1 MJ for a compression laser and a heating laser, respectively, at 16 Hz repetition rate and 17% electrical-optical efficiency. We have proposed two new technologies into the laser system to improve its laser output characteristics dramatically. One is cryogenic Yb:YAG ceramics as a laser mat...
متن کاملResearch and Development Assessments for Prometheus Heavy Ion and Laser Driven Inertial Fusion Energy Reactor Designs
Research and development assessments for two inertial fusion energy (IFE) reactor design concepts developed in the Prometheus study are presented in this paper. The assessment here focuses on resolving the technical issues identified for the critical components unique to IFE: target, driver, and cavity/first wall. The two designs considered are based on heavy-ion and laser drivers.
متن کاملA Laser Based Fusion Test Facility
The Fusion Test Facility (FTF) is a high repetition rate ignition facility that would bridge the gap between single shot facilities (such as NIF and LMJ) and a fully functioning laser fusion power plant. It would allow development of science and technologies so that follow-on power plants could have predictable performance. The FTF would need to have enough fusion power, about 100 MW, to rigoro...
متن کاملEnergy Gain of Magnetized Cylindrical D-T Targets in Fast Ignition Fusion
In recent years, many different plans have been considered to use the nuclear energy gained from inertial confinement fusion (ICF) as attempts to obtain high energy efficiencies. In conventional ICF methods, a small amount (about mg) of the deuterium–tritium compound is confined in a small spherical chamber of a few millimeters in radius and compressed by laser or heavy ion beams with powers in...
