Abstract

This is a report on the characteristics of the large aperture Nd:YAG disk laser with dimensions of 6x40x80 mm. The product of small signal gain coefficient and the long axis the disk without clading absorption glasses was limited to less than 1.36 because of the severe parasitic oscillations. The Nd:YAG crystal boule grown by the temperature gradient technique (TGT) has 75-80 mm in diam. and 133 mm long. The Nd doped concentration can be up to 2.3 Wt%. Now the clading absorption coating is considered to be used in the disk laser system and further results will be reported.
