Zusammenfassung:A 780 nm high power laser source prototype for Rb atomic precision measurement is reported. The prototype uses a single 1560nm fiber laser with linear polarization, narrow linewidth and broadband tunable frequency as the seed source. By effectively improving the output power of the fiber amplifier, the 780nm laser power generated by PPLN frequency doubling is up to 2.25W. With the saturated absorption frequency stabilization technology of sideband locking, the center frequency of the high power 780nm laser can be stabilized within ± 150kHz for a long time, and it can accurately tune 1.2GHz, with the linear polarization up to 23dB. The prototype is easy to operate and can be transported, which is very suitable for precise measurement of Rb atoms.
