A fiber-coupled laser-diode (LD) end-pumped Nd:GdVO_4 slab continuous-wave (CW) 912-nm laser and an LD bar end-pumped Nd:GdVO_4 slab CW 912-nm laser are both demonstrated in this paper.Using the fiber-coupled LD of end-pumped type,a highest CW 912-nm laser output power of 10.17 W is obtained with a high optical-to-optical conversion efficiency of 24.6% and a slope efficiency of 34.5%.The measured M 2 factors of beam quality in x and y directions are 5.3 and 5.1,respectively.Besides,an LD bar of end-pumped type is used to realize CW 912-nm laser output,which has the advantages of compactness and low cost.When the pump power is 38.8 W,the output power is 8.87 W and the measured M 2 factors of beam quality in x and y directions are 16 and 1.31,respectively.In order to improve the beam quality of the 912-nm laser at x direction,a new quasi-concentric laser resonator will be designed,and an LD bar end-pumped Nd:GdVO_4 slab high-power CW 912-nm TEM_(00) laser will be realized in the future.
