Single mode GaSb diode lasers for sensor applications in a long wavelength regime

The wavelength, λ, range of 1.8  μm≤λ≤3.5  μm contains strong spectral absorption lines of many gases used in health, industry, safety, and medicine and whose sensitive and quantitative detection is desirable. However, the performance of InP diode lasers markedly deteriorates beyond λ∼2  μm. In this...

Description
Summary:The wavelength, λ, range of 1.8  μm≤λ≤3.5  μm contains strong spectral absorption lines of many gases used in health, industry, safety, and medicine and whose sensitive and quantitative detection is desirable. However, the performance of InP diode lasers markedly deteriorates beyond λ∼2  μm. In this paper we present new results on developing tunable high power single mode laser diodes based on the GaSb material system with emission in the wavelength range of 1.8  μm≤λ≤2.2  μm.
