摘要：

Sensitivity detection of oxygen at high temperature is reported using a simple spectrometer based on a DFB-laser. Measurements for the (R)R(N = 7) and the (R)R(N = 9) magnetic dipole transitions of the b(1) Sigma(g)(+) (v' = 0) <-- X(3) Sigma(g)(-) (v '' = 0) band at 761 nm were performed from a few Torr to atmospheric pressure and for different temperatures up to 400 degrees C. Self-broadening and N-2-broadening coefficients were extracted, and their dependence on the temperature was investigated.
