Design and implementation of a low power consumption, small size, long-term stable operation of automatic frequency stabilization laser system. By designing and implementing a high efficiency and low ripple voltage source, the power consumption and the volume of the whole system are greatly reduced. The linewidth is obtained by designing and implementing a high-performance temperature control circuit, a current control circuit and a frequency stabilization circuit Narrow, higher frequency output laser. The system can automatically long-term frequency stabilization, the output laser linewidth of about 1 MHz, the stability index for the second stability of 1.43 × 10 ~ (-10), ten seconds of stability 3.90 × 10 ~ (-11), hundred seconds of stability 1.28 × 10 ~ (-11), thousandths of stability 2.25 × 10 ~ (-11). Under the precondition that the stability is slightly better than commercial external-cavity semiconductor laser, the power of the laser system is reduced by about 85%, and the power consumption of the whole machine is reduced by about 90%. In order to realize low power consumption and miniaturization of the semiconductor frequency-stabilized laser system Provide a new program.
