Abstract

Ultraviolet ultra-short pulse laser has incomparable advantages in strong field physics and fast ignition of inertial confinement nuclear fusion. In addition to the short wavelength and strong focusing ability, UV laser has a larger critical density and is closer to the over-dense fuel target region, thus simplifies all the process relates to the energy transport. Based on the I-λ 2 scaling law, ultraviolet laser is enough to produce hot electrons with the temperature required for fast ignition. Meanwhile, excimer laser has unique advantages in amplifying ultra-short pulses. In order to increase the laser energy irradiating on the target, the amplifier with larger energy cross section and higher energy extraction capacity are required. In this paper, a method of beam combination amplification of ultraviolet ultrashort pulse laser in a discharge-pumped excimer laser amplifier has been explored by conjugated polarization, and the feasibility of applying this technique to excimer laser is verified.
