SideKick QCL Controller: Precision Low-Noise Laser Management

The SideKick Laser Controller marks a notable advancement in quantum cascade laser controller innovation, boasting enhanced design, features, and performance. Its quiet operation eliminates the need for cooling fans, while its drive electronics, combined with a compatible DRS Daylight Solutions laser head, deliver unparalleled Continuous Wave (CW) Relative Intensity Noise (RIN) performance.

With its foundation in the tested functionality of TLC/FLC controllers, the SideKick controller is compatible with various laser systems and wavelengths. The Hedgehog, CW-MHF, Aries-100, and Unicorn-II laser heads, as well as the older Pulsed, CW/pulsed, and Über Tuner™ heads, are among the product families from the 31000 and 41000 series that it is compatible with.

With HFQDTM circuitry, which has been shown to preserve laser chips, the SideKick controller offers accurate and flexible control over laser power, wavelength, temperature, scan speed, and pulse parameters.

Customers may enjoy many tuning and triggering modes, elegant local/remote control, diagnostics, and USB/Ethernet connectivity with the SideKick controller, which also comes with an SDK and GUI.
