摘要：
We report a coherent radiation at 494.5 nm by intra-cavity sum-frequency generation of 912 nm Nd:GdVO4 laser and 1080 nm Nd:CaYAlO4 laser. Blue laser is obtained by using a doubly folded cavity, type-II critical phase matching KTP (KTiOPO4) crystal sum-frequency mixing. With total pump power of 33 W (13.8 W pump power for 1080 nm Nd:CaYAlO4 laser and 19.2 W pump power for 912 nm Nd:GdVO4 laser), TEM00 mode blue laser at 494.5 nm of 1.6 W is obtained. The power stability in 30 min is better than 3.5%. (C) 2014 Elsevier GmbH. All rights reserved.
