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 Gd_xY_1-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 Gd_xY_1-xCa₄O(BO₃)₃ (x equals 0.24).
