We have stabilized Nd:YAG lasers at 1064 nm and 1319 nm by frequency locking the doubled output to 127I2 transitions in the visible. Frequency stability of 2.5 parts in 1013 in a measurement time of 32 s isreached by resonant second harmonic generation and locking to iodine hyperfine lines at 532 nm. Locking to
Doppler-broadened lines at 532 nm provides a frequency stability of 2 parts in 1011 using a relatively simple,low-power frequency locking scheme. Single-pass second harmonic generation of the 1319 nm Nd:YAG laser in a quasi-phase-matched waveguide and locking to iodine transitions at 659.5 nm may provide a wavelength and frequency reference for fiber-optic communication and sensing systems
