Abstract :
Investigation of the congruent melting rare-earth aluminum garnet Gd3 Sc2 Al3 O12 (GADSCAG) has been made. The optimum crystal growth parameters for the undoped material are a rotation rate of 20 r/min and a growth rate of 4.6 mm/hr along the 
direction. For Nd3+-doped crystals the linear growth rate is 2 mm/h. The optical properties of Nd:GADSCAG which are of interest for laser operation were also determined. The stimulated emission cross section of the 1.06-μ transition in Nd3+at room temperature is 
cm2, the fluorescence lifetime is 
s at an Nd3+ion density of 1 atomic percent in the crystal and the integrated peak absorption cross section in the strongest pump band (0.81 μ) is 
cm2, A comparison of the CW laser performance of identical ND:YAG and Nd:GADSCAG rods is presented.
