Abstract

This paper deals with development of novel single-frequency tunable diode laser with fiber-optic output for gas-analysis applications. The approach we proposed is convenient, simple and cheap solution for spectroscopy of a single absorption lines of any gases having absorption bands in the optical fiber transparency window (0,7 ÷ 1,7 μm). The presence of fiber-optic output is an additional advantage for remote sensing applications. The laser operation was demonstrated in the case of the line R7 of methane absorption band 2v₃ at wavelength λ=1,645 μm. The mode-hop-free tuning range of 35 GHz (1,2 sm^-1) was achieved.
