title: Frequency Stabilization of a Diode Laser at 1540 nm by Locking to Sub-Doppler Lines of Potassium at 770 nm.
abstract: An external cavity 1540-nm diode laser was frequency doubled in a 3-cm-long periodically poled LiNbO(3) waveguide doubler with 150% W(-1) conversion efficiency, thereby generating more than 3 muW at 770 nm. Second-harmonic light was used to detect and lock to sub-Doppler lines of the (39)K D(1) transition.
