  |   | Sponsored  |  |  The Laser Lock Pro (LLP-100) 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.  |
