Paper Abstract

In this study, yttrium calcium oxyborate, YCa4O(BO3)3 (YCOB) was grown and investigated as a nonlinear optical material. This crystal is phase-matchable for the third harmonic generation (THG) of a Nd:YAG of a Nd:YAG laser by type-I mixing between 1.064 and 0.532 micrometers . By partial substitution of Gd for Y in YCOB, a solid solution GdxY1-xCa4O(BO3)3 gradually changes the phase-matching angles of THG to ((Theta) , (phi) ) equals (90 degrees, 90 degrees). In this paper we present the properties of noncritically phase-matched THG in GdxY1-xCa4O(BO3)3 (x equals 0.24).
