摘要：

Lead-salt diode lasers have been commercially available for more than two decades and became essential for laser mid-infrared gas analysis with high sensitivity and selectivity. Their emission covers the wavelength range from below 3 mum to more than 20 mum. Continuous emission is observed to above 200 K, and pulsed emission to above 80 degreesC. Their main advantage over other materials is a two orders of magnitude lower Auger recombination rate. Basic material properties, the present state-of-the-art lead-salt lasers and trends and possibilities are discussed.
