Abstract
A simple and easy to implement digital technique for frequency locking of a pair of diode-pumped solid state lasers is presented. The beat f requency of the two lasers, suitably prescaled, is compared to a refer ence oscillator. The error signal is used to drive the slave laser via its in-built PZT. An Allan variance of 1 part in 10(-6) over a typica l measurement time of 0.1s, over the whole range of synthetic waveleng ths of interest, proves the effectiveness of the locking system.
