D2-135 Offset Phase Lock Servo Configuration

Typical use of the D2-135 OPLS offset locks a slave laser (blue components) to a master laser (red components) which has been locked to a primary frequency standard such as the D2-210 Saturated Absorption Spectroscopy Module by a D2-125 Reconfigurable Servo.  In this figure, the optical beat note is generated in the D2-250 Heterodyne Module (purple) , converted from an optical to an electrical beat note by the D2-160 Beat Note Detector and delivered to the D2-135 via a multimode fiber.
