Über Tuner™ Broad Tuning Pulsed Lasers

Daylight Solutions is proud to offer the Über Tuner™ series of broadly tunable ECqcL™ (External Cavity quantum cascade Lasers). These pulsed lasers allow unprecedented access to high-brightness coherent light in the mid-IR. We now offer up to 350 cm-1 or 2.4 µm of tunability from a single-chip platform with narrow linewidth and easy tunability. The Über Tuner™ also offers higher powers – up to 400 mW.

The broad tuning of the Über Tuner™ series lasers are just right for sensing and stand-off detection experiments as well as solid and liquid phase spectroscopy and imaging. Daylight Solutions - The source for all applications in the Mid-IR.

The Über Tuner™ product series have been enhanced to offer even more tunability per system. The ÜT-10 now offers ≥2.4 µm of tunability from 10.0 to 12.4 µm.

Product Details

Daylight Solutions is pleased to provide the Über Tuner™, the next generation in broadly tunable mid-IR lasers based on quantum cascade technology. Tunability spans the mid-IR spectrum from 4 μm to 12.4 μm with continuous tuning of up to 350 cm-1. All lasers offer superb wavelength accuracy and stability throughout their tuning range.
Designed by the world’s leading experts in tunable lasers, these sources are small, robust, and utilize specially-designed patented[1] micro-lens system to optimize system performance. Each system integrates TEC technology for behind-the-scenes temperature control, so no cryogenic or water cooling is required.
Each Über Tuner™ ships with a compact, next-generation SideKick controller. SideKick provides flexible, precise control of laser: power; wavelength; temperature; scan speed; and pulse parameters. And all while protecting your gain chip with Daylight’s proven High-Fidelity Quantum Cascade Drive (HFQD™) circuitry. SideKick’s USB/Ethernet connectivity also provides elegant local/remote control and diagnostics, and multiple wavelength tuning and triggering modes.
Daylight Solutions’ overall system leverages the last 15 years of tunable laser development and manufacturing, and incorporates the company’s latest patented[2] tuning and packaging technology for the mid-IR.
The performance of the world’s leading broadly tunable lasers in the 4 μm to 12 μm region of the spectrum has now been expanded. The new Über Tuner™ offers the broadest coverage in a single-chip system.
Common applications include industrial process control, the detection of biomarkers in the breath, cellular imaging, and the detection of chemical and biological agents. These lasers enable application research in the field of molecular detection and imaging, stand-off detection and molecular spectroscopy. 
Daylight Solutions' mid-IR laser platform technology opens up the mid-IR to all researchers—today.
