Overview
The SMC-Series modules are the ideal instruments for controlling the current and the temperature of narrow linewidth laser diodes. With an ultra-low noise current sink (SMC11) and sub-mK thermal control stability (SMC20 & SMC31), the SMC-Series is the right choice for the most demanding applications. Because SMC-Series was first designed for frequency stabilization and OPLL applications, the SMC11 current sink also provides two current modulation inputs since ultra-low noise current and fast current modulation are key parameters for achieving the best phase noise performance of your stabilized lasers. Using the SMC-Series laser diode controller with the SMA- or SMB-Series modules, complete turn-key solutions are available for your laser frequency stabilizations or phase-locked lasers.
