Frequency stabilization of a diode-pumped Nd:YAG laser at 532 nm to iodine by using third-harmonic technique


A compact frequency standard was constructed by stabilizing the frequency of a diode-pumped Nd:YAG laser to the Doppler-free spectrum of iodine at 532 nm. The results show that by using standard third-harmonic locking technique good stability can be achieved in a relatively small, simple and inexpensive set-up.
