title: Quasi-phase-matched frequency doubling in a waveguide of a 1560-nm diode laser and locking to the rubidium D(2) absorption lines.
abstract: An external-cavity 1560-nm diode laser was frequency doubled in a 3-cm-long periodically poled LiNbO(3) waveguide doubler with 120% W(-1) conversion efficiency. The 780-nm light was used to detect the D(2) transitions of Rb, and the laser frequency was locked to Doppler-broadened lines of Rb. Furthermore, the ~1 microW of second-harmonic power was sufficient for detecting the sub-Doppler lines of Rb, and the laser was locked to a (87)Rb crossover line.
