Molecular spectroscopy applications benefit from rapid, high Signal-to-Noise Ratio data acquisition. This demands fastscan mid-IR lasers delivering high-quality light. Until now, high tuning speed has come with compromises. The new Hedgehog from DRS Daylight Solutions changes this. For the first time, fast tuning and high-fidelity output is available from a compact, robust mid-IR laser. Hedgehog is built on Daylight’s field-proven Quantum Cascade Laser (QCL) technology. Available center wavelengths span the mid-IR spectrum from < 4 μm to >13 μm, and Hedgehog can provide pulsed or CW output. Users can select from three model types (HHG, HHGUT, or HHG-LT) depending on their application power and tuning range requirements. All models include a GUI option for ultra-quiet CW operation, high wavelength repeatability, and multiple tuning modes.
