摘要：
We designed and realized a compact laser system of which the frequency can be automatically stabilized. The laser system can operate with low power consumption and long-term stability. The power consumption and the volume of the system are reduced through our designed voltage source with high efficiency and low ripple. With the high-performance temperature controller, current controller and automatic frequency stabilization modules, a laser with narrow linewidth and high frequency stability is realized. The linewidth is about 1 MHz, and the frequency stabilities at 1, 10, 100, 1000 s are 1.43×10-10, 3.90×10-11, 1.28×10-11, 2.25×10-11, respectively. Compared with the commercial external-cavity diode lasers, the designed system has better long-term frequency stability. The volume of the power supply for the system is reduced by 85%, and the power consumption is reduced by 90%. The system is a new scheme for realizing low power consumption and miniaturization of the frequency-stabilized semiconductor laser system. © 2016, Chinese Lasers Press. All right reserved.
