The temperature-based frequency stabilization of internal cavity Nd:YVO4 microchip laser is studied. The factors that affect the frequency of Nd:YVO4 microchip laser and the impact of frequency drift on the measurement accuracy are analyzed. Physical device and control circuit are designed. The stabilization of the frequency is realized by control of the temperature. The components of the system and the role of each component are introduced. The frequency and the power are experimentally analyzed. On the base of this,the structure of the system is optimized. The frequency stability is obliviously improved by employing the temperature control,which can reach the level of(10^(-7)~10^(-8)). The working performance of the instrument is improved to fulfill the need of precise measurement,so that it has a broader development prospects in the field of precision measurement technology.
