Paper Abstract

Tunable diode lasers have a wide range of applications based on their unique combination of features, including high spectral purity, high spectral brightness, tunability, ease of modulation, small size and complete coverage of the important 3-30 μm spectral range. Demonstrated applications include rapid spectral measurements with a resolution better than 10-4cm-1 and sensitive detection of atmospheric pollutants over kilometer path lengths. Tunable diode lasers are forming the basis of a new class of infrared analytical instruments with applications in many areas of measurement and analysis. This paper will review the properties and uses of tunable diode lasers and describe a number of recent developments of particular significance, including CW operating temperatures as high as 100K for many spectral regions, temperature tuning ranges greater than 300 cm-1 and CW power outputs in excess of 100 milliwatts. Potential applications in a number of new areas will be discussed.
