While semiconductor diodes currently dominate the world market for near-IR lasers, longer-wavelength devices emitting beyond 3 μm have yet to achieve adequate performance levels. Practical mid-IR systems will ultimately require high-power non-cryogenic sources that operate either cw or quasi-cw with a high duty cycle. Key applications include chemical and biological detection, laser spectroscopy, laser surgery, and infrared countermeasures against heat-seeking missiles.
