Abstract
A system and method that can be employed to lock and scan the output of a laser cavity () is described. The system and method involves the use of a signal generator for generating an error signal between an output of the laser cavity () and the transmission () of the laser through a tunable external reference cavity (). A dual piezo-actuated mirror () permits processing of the error signal () with separate signal processing circuits () used to provide an electrical feedback signal to the two piezo-electric crystals (). When incorporated within a laser cavity the described system and methodology can be used to lock and scan the output of the laser cavity while providing the laser output with a reduced linewidth.
