摘　　要：We propose and make a compact yellow-orange laser of the Nd-doped yttrium vanadate(Nd:YVO_(4))/periodically poled Mg-doped lithium niobate(PPMgLN)module by Raman frequency-doubling at 589 nm.By reasonably designing the size of the Nd:YVO_(4)and 5 mol%PPMgLN crystals,cavity length and coating parameter,a compact 589 nm laser module with a total size of 3 mm×10 mm×1.5 mm is fabricated.In the laser module,the input surface of Nd:YVO_(4)crystal is end-pumped by an 808 nm laser diode(LD).Under the effect of linear resonant cavity structure,the output surface of PPMgLN crystal with a period of 9.48μm generates 589 nm yellow-orange light.The experimental results show that the maximum output power at 589 nm is 390 mW at the pump power of 3 W with the optical-optical conversion efficiency of 13%and the stability of the output power is less than 2%within 3 h.
