An offset laser lock is an optoelectronic system capable of stabilizing a laser's optical frequency to a variable offset from another stable laser's frequency. The lock system described in this report relies on a digital frequency comparison of the beat note of two lasers to determine and fix the frequency difference, or offset, between them. This thesis describes the construction of a configurable proportional-integral (PI) control circuit to regulate a laser's frequency based on the error signal generated by a digital comparison of the beat note frequency, as well as the integration of formerly unconnected circuit elements within the laser lock. Testing confirms the proper operation of both the PI circuit and the laser lock system.
