The Firefly-IR LW from M Squared is a Ti: Sapphire Tunable Pulsed Laser that operates from 5.6 to 8.5 µm. It provides an output power of 30 mW with a pulse duration of 50 ns and has a pulse repetition rate of up to 20 kHz. The laser has a beam diameter of 10 mm with a beam divergence angle of 3 mR and has a linewidth of 15 cm-1. It is available in a compact module that measures 430 x 160 x 70 mm and is ideal for real-time imaging for molecular spectroscopy, the remote sensing of hydrocarbons, stand off-gas detection, and mid-IR waveguide characterization applications.
