Middle Infrared lasers (2-5µm) are in great demand for a variety of applications including plastic and polymer processing, spectroscopy, non-invasive medical diagnosis, laser scalpel, remote sensing, free space communications and pumping OPOs. Numerous defense related applications include countermeasures, stand-off detection of explosion hazards, eyesafe seekers for smart munitions, and covert communications systems. Lasers based on IPG's TM:ZnSe/S crystals are the sources of choice when one needs a system that is compact, efficient, robust, powerful, and continuously tunable over a broad spectral range.
