Abstract

An external-cavity 1560-nm diode laser was frequency doubled in a 3-cm-long periodically poled LiNbO₃ waveguide doubler with 120% W⁻¹ conversion efficiency. The 780-nm light was used to detect the D₂ transitions of Rb, and the laser frequency was locked to Doppler-broadened lines of Rb. Furthermore, the ~1 μW of second-harmonic power was sufficient for detecting the sub-Doppler lines of Rb, and the laser was locked to a ⁸⁷Rb crossover line.
