AgGaSe2 crystal of φ20×60 mm has been grown by the method of oven temperature drop. The frequency-doubled (5.3 μm) output and the power conversion efficiency of 1.12% have been obtained for second harmonic generation of TEA CO2 laser (10.6 μm). The pumped and the damaged threshold are about 3 MW/cm2 and 11 MW/cm2, respectively. We have also discussed the effect of the beam divergence on the second harmonic conversion efficiency.
