THL-100 multi-terawatt laser system of visible spectrum range
Abstract
The results of experimental studies aimed at increasing the power of THL-100 hybrid laser system are presented. The laser system consists of Ti:Sa front-end, operating at the central wavelength of 950 nm, second harmonic generator (SHG), prism stretcher, gas XeF(C-A) amplifier, and compressor based on fused quartz plates. In these experiments the SH spectrum broadening in a nonlinear crystal was realized, which allows to reduce its pulse duration from 50 to 30 fs. This radiation pulse was extended in the prism stretcher to 1.8 ps and amplified in the XeF(C-A) amplifier. At the output of amplifier 1.2 J energy was obtained. After compression, this laser pulse had duration of 29.4 fs and peak power of 40 TW. It is the second highest peak power value in visible spectrum range.
