Abstract
A 1560 nm external cavity diode laser was efficiently doubled in a periodically poled LiNbO3 waveguide and locked to 87Rb sub-Doppler lines near 780 nm. Its frequency stability was characterized by measuring the beat frequency relative to a 780 nm external cavity diode laser which was locked to sub-Doppler lines of another Rb cell. The root Allan variance reached a minimum value of 6.9 X 10-12 in 1 s, which corresponded to frequency variations of 1.3 kHz for the 1560 nm laser.
