Abstract

Solid state tunable laser crystal can play a much more important role than liquid dye in ultrafast laser, and probably in high power lasers. In this paper, the recent progress in our laboratory on the tunable laser crystals containing paramagnetic ions such as Ti³⁺ of 3d¹ configuration and Cr^4$PLY of 3d² configuration, are reported here. In the case of the former, two new techniques have been invented to produce high quality Ti-doped sapphire crystal, they named by induction field up-shift method (IFUM) and temperature gradient technique (TGT), which differ from the traditional Czochralski Method and heat exchange method. The high merits of IFUM and TGT Ti:Al₂O₃ crystals have been demonstrated, and especially the laser operations have been performed very well by using them. In the latter case, the special attention of our laboratory has been paid on the recent experimental results of quadravalent chromium ion doped near-IR tunable laser crystals, which include YAG, forsterite, and also some new laser hosts such as SGGG, and LGO, etc. Their spectroscopy and laser characteristic have also been discussed.
