Paper Abstract

We have constructed two kinds of table-top femtosecond terawatt (TW) Ti:sapphire laser systems based on the chirped-pulse amplification (CPA). With a compact design using only two-stage amplifiers, output energies of 36mJ and 640mJ at 10hz repetition rates were obtained with recompressed pulse duration of 25 fs, and 31 fs respectively, corresponding to peak powers of about 1.4 TW and 20 TW. The total pump energy for the last stage is 260 mJ and 2.8 J at wavelength of 532 nm. These results represent a significant efficiency in amplification and a compact configuration in size. By using an adaptive optical system to correct the wave-front distortion of the 20TW laser. we further demonstrated the improvement of beam quality br higher focusable laser intensity.
