SideKick QCL Controller

Low-Noise Laser Controller

The SideKick™ Laser Controller represents a significant step forward in the design, features, and performance of quantum cascade laser controllers. Its low-noise design means no cooling fans, and when paired with a suitable DRS Daylight Solutions laser head, its drive electronics enable industry-leading CW RIN (low optical noise).

Built on the proven performance of our TLC/FLC controllers, the SideKick controller supports a wide range of our laser systems and wavelengths. It is compatible with all 31000- and 41000-series product families, including the Hedgehog™, CW-MHF™, Aries-100™, and Unicorn-II™ laser heads as well as older Pulsed, CW/pulsed, and Über Tuner™ heads.

The SideKick controller provides flexible, precise control of laser power, wavelength, temperature, scan speed, and pulse parameters—all while protecting your laser chip with our proven HFQD™ circuitry.

The SideKick controller includes a GUI and SDK plus USB/Ethernet connectivity, providing you with elegant local/remote control and diagnostics, and multiple tuning and triggering modes.
