A compact frequency-stabilized laser system at 589 nm is demonstrated for sodium laser guide star and sodium lidar. The 589 nm laser based on all-fiber devices was generated by the sum frequency generation (SFG) of the distributed-feedback laser diodes (DFB-LD) seed lasers of 1064 nm and 1319 nm. The absolute frequency was locked to the D2a line by adopting the method of saturated absorption. The frequency drift of 589 nm can reach to 1.8 MHz (RMS) over 5000 s. The proposed DFB-LD based frequency stabilization scheme of 589 nm laser is a promising solution for applications that require extremely mobile or miniaturized systems. [ABSTRACT FROM AUTHOR]
