Abstract
Our pulsed Ti:S laser is abaxial longitudinally pumped by a frequency double YAG laser with VRM unstable resonator, the Ti:S crystal is Bi-Brewster-cutting. The single output energy of the Ti:S laser is over 130 mJ at 1 Hz and over 110 mJ at 10 Hz, the efficiency is 39.6% and 36. 7% respectively, the tunable range is 0.723 approximately 0.996 micrometers with only a pair of flat mirrors, the output energy in the two ends is 1/10 of that in the center wavelength. We discuss the effect of choice of the crystal size, the angle (alpha) (between the pump beam and the cavity axis) on efficiency. We suggest that the high absorptivity, high FOM value of the crystal bring high output and high efficiency when longitudinally pumped by a flat-top laser beam. We also show the scheme of our Ti:S laser and our broad band transmitted curve of reflective mirror.
