Abstract—We report a continuous-wave (CW) yellow laser emission by sum-frequency mixing in Nd:YVO₄
crystal. Using type-II critical phase-matching KTP crystal, a yellow laser at 593.5 nm is obtained by 1064 and
1342 nm intracavity sum-frequency mixing. The maximum laser output power of 2.1 W is obtained when an
incident pump laser of 18.2 W is used. At the output power level of 2.1 W, the output stability is better than
3.2%.
