A cruciform cavity is presented for multi-wavelength laser generation. On the basis of considering the optimal power ratio and good spatial overlap of the two fundamental beams, the maximum output power of 589 nm laser reaches 3.5 W when the pumping power of Nd:YAG A and Nd:YAG B are 311.5 W and 261.8 W, respectively.At the same time, the other wavelength lasers are also obtained with the output power distribution of 2.5 W at66Onm, 15 W at 532nm, 1OOmW at 1319nm and 240mW at 1064nm. The corresponding beam quality factors are M2x= 4.93, M2y = 5.01 at 589nm, M2x= 4.51, M2y = 4.85 at 660nm, and M2y= 4.12, M2y= 3.96 at 532nm,respectively. The instabilities of the three visible lights are measured, which are also less than 2% within three hours.
