Abstract
A stable laser with F +3 and F2 mixed color centers in LiF crystal is constructed using a transversely pumped cavity at room temperature. The mixed color center laser is pumped with a nitrogen-laser-pumped dye laser. A pulse output of the laser is 0.23 mJ. The pulse widths of the F +3 and F2 color center lasers are about 12 and 8.5 ns, respectively. The optical–optical conversion efficiency is about 5.0%. The divergence of the F +3 color center laser beam is about 2.2 mrad and that of the F2 color center laser beam about 3.5 mrad. The polarization of the mixed color center laser is about 0.97. The output of the F +3 color center laser extends from 515 to 575 nm and peaks at 540 nm, while that of the F2 color center laser extends from 633 to 705 nm and peaks at 667 nm.
