Multi-function, external cavity quantum cascade laser controller with industry-leading noise performance.

Welcome to SideKick™ – Daylight Solutions' new quantum cascade laser controller. SideKick is a next-generation design that builds on the field-proven success of our TLC/FLC control electronics. SideKick supports Daylight's broad range of external cavity quantum cascade laser (ECqcL™) systems 2, functionality, and QCL wavelength selection. SideKick represents a significant evolution in controller features and performance, and is compatible with all 31/41xxx Pulsed, CW-Pulsed, ÜberTuner™ and Mode-Hop-Free laser heads 2. SideKick allows flexible, high-precision and high-stability control of laser: output power; wavelength; temperature; scan speed (to >1000 cm-1/s 3); pulse width, repetition rate and duty cycle (up to 1 µs, 3 MHz and 30% respectively) 3,4. And all while protecting your gain chip with Daylight's proven High-Fidelity Quantum Cascade Drive (HFQD™) circuitry.

Signal-to-Noise is critical in most MWIR applications, and laser performance is only as good as controller performance. Recognising this, SideKick's design emphasises low noise and, when paired with a suitable laser head, produces extremely low RIN 5. With a compact form factor and USB/Ethernet connectivity, SideKick is ideally suited to OEM integration and laboratory use. The included GUI 6 and SDK provide elegant local/remote control, error messaging, and also allow user-programmable tuning, swept scans, step-and-measure scans, and multiple triggering modes. With a SideKick in your Daylight laser system, you'll find your mid-infrared applications easier than ever before. Just connect SideKick to your PC, laser head and go! Please contact us to learn more.

[1] All specifications are: defined after a 10-minute warm up; subject to change without notice.
[2] Not compatible with 31/41xxx fixed-wavelength (Aries, Unicorn) or 11/21xxx laser heads, which require designated TLC/FLC controllers.
[3] Depends on laser head and/or gain chip - please enquire.
[4] Laser operation above 10% duty cycle requires a suitable QCL chip and may require supplemental cooling of the laser head - please enquire.
[5] Typical RIN as low as -150 dBc/Hz was measured in the range of 400 kHz to 1 MHz using SideKick with a TLH-41060-MHF laser head.
[6] GUI compatible with Windows® 7, 8.1 & 10. Please enquire for other OS.
