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.

Our External Cavity Diode Lasers (ECDLs) work perfectly with our ILC and SILC controllers.

Our SILC has all the functionality of the ILC, plus makes it easy to lock the laser to an atomic line or reference cavity.
