Iodine spectroscopy and absolute frequency stabilization with the second harmonic of the 1319-nm Nd:YAG laser.
We have frequency doubled a 1319-nm Nd:YAG laser in a quasi-phase-matched LiNbO(3) waveguide and used the asymptotically equal to1-mW second-harmonic output to investigate the (127)I(2) transitions near 660 nm. We reached submegahertz laser-frequency stability at a (vacuum) wavelength of 1319.098 nm by locking the second harmonic to the center of the P(48)6-6 transition.
