Santec introduces laser servo controller for enabling stabilization of tunable lasers

SANTEC, a leading manufacturer of advanced optical components, tunable lasers, optical test equipment, and OCT systems, announces the release of a new product, the Laser Lock Pro (LLP-100). It is designed to complement Santec’s external cavity tunable lasers, as a servo controller to stabilize the laser’s oscillating frequency. LLP-100 locks the laser wavelength to an external reference. The LLP-100 is software controlled to easily adjust and lock the frequency to a desired reference such as a gas absorption cell, Fabry-Perot cavities or other frequency reference. Frequency locking supports both the Pound-Drever-Hall (PDH) method and the side-fringe locking methods. The LLP-100 coupled with the TSL-570 is an ideal system for applications requiring both wavelength tunability and frequency stability; for example: continuous comb generation using a microcavity on a silicon photonics chip as well as quantum applications to stabilize the laser at arbitrary wavelengths.
