    • Description
    • Additional information


    AOSense has developed a compact Integrated Laser Controller (ILC) that can be paired with our External Cavity Diode Lasers (ECDLs) to control laser current, piezo transducer (PZT), and temperature. The ultra-low noise electronics are fully digitally controlled. The ILC dimensions are only 5″x2.9″x0.95″. We provide software with an easy-to-use graphical user interface (GUI) that can control multiple lasers from a single window. If preferred, commands may be sent over a USB virtual COM port. The software screenshot below (click the image to enlarge) shows the interface including a plot of the temperature (green line) as it settles to a commanded value.
