Abstract
A Pb-salt tunable diode laser (TDL) has found many applications in the field of atmospheric gas analysis. Its continuous tunability and fine spectral purity in the mid infrared region are outstanding from other lasers. The only shortcoming is that it requires cryogenic operating temperature, though it is improved year by year towards the room-temperature operation. Nevertheless, a repeated pulse operation of Pb salt diode lasers is possible with a thermoelectric cooling device.
