Upconversion fluorescence in Nd:YVO4 crystal under a laser diode (LD) pump was investigated. It is proved that the predominant mechanism for excitation of 4G7/2 level is an energy transfer upconversion. Then,a theoretical approach to upconversion effect on LD pumped Nd:YVO4 laser is given.In addition,the role of upconversion in thermal effect is discussed in detail.
