Abstract
The method to determine the spatial configuration of GdCa4O(BO3)(3) (GdCOB) crystal is introduced. Samples are cut in and out of principal planes for type I phase matching. Their second-harmonic-generation (SHG) conversion ef ficiency is measured by a mode-locked Nd:YAG laser. The intracavity doublin g frequency of GdCOB crystal is reported for the first time. At the inciden t pump power of 10 W. the 532 nm output reaches 1.22 W with the (113.2 degr ees. 47.4 degrees)-cut sample. In conclusion, the (113.2 degrees, 47.4 degr ees)-cut sample shows more excellent SHG property than those cut in other d irections. (C) 2001 Published by Elsevier Science B,V.
