Abstract

Laser frequency locking apparatus (5), comprising: a slave laser (15), having associated with it means (14, 18) for coupling and/or means (118, 25) for coupling and propagating signals received and emitted; a phase lock loop (24); and a controller (16), operable to control the slave laser, wherein an output of a reference signal source (1) associated with a master source (2, 3), and receivable therefrom, is utilised in the phase lock loop to render the output frequency of the slave laser the same as an output frequency of the master source. The invention described relates to a technique for generating a set of highly stable optical frequency channels. There are provided methods and systems of locking laser frequencies and of synthesizing frequencies.
