Abstract(in English) This paper presents CW lasing characteristics of Nd:KGW with different doping concentrations. Three samples with Nd^<3+> doping of 3, 5 and 10 at.% were pumped by a Ti:sapphire laser. The 3 at.% sample exhibited the highest efficiency of 57% at a wavelength or 1.067μm compared with other two samples. The same 3 at.% sample was pumped a 1 Watt LD and a high slope efficiency of 47% was achieved. The measured fluorescence lifetime for the 3 at.% is 109μs, however, as the doping level is increased , the fluorescence lifetime also decreases. Also, this paper will present the first reported CW lasing at 1.351μm of a 3 at.% using a Ti:sapphire laser.
