Toptica Photonics’ DigiLock 110 is a digital module for laser control and frequency stabilization. It also can be used to control and analyze the laser digitally. Functions include side- and top-of-fringe locking, and signal visualization and analysis. In auto lock mode, the user can modify the scan parameters of the laser by dragging the mouse and zooming into a feature of a spectrum on the software oscilloscope screen. With the feature displayed, the user can “click & lock” to any peak or slope. The field-programmable gate array-based hardware makes the system flexible and fast. The unit has numerous inputs and outputs, up to a 100-MHz sampling rate and up to 21-bit precision. Total delay time is <200 ns, and the digital locking bandwidth is several megahertz.
