A tunable multimode unidirectional traveling-wave Ti:sapphire laser was developed to measure in situ the atmospheric absorption spectra using intracavity absorption spectroscopy. The effective absorption path length was 2100 km. ${\mathrm{O}}_2$ and ${\mathrm{H}}_2\mathrm{O}$ vapor lines in atmosphere with absorption coefficients of ${10}^{-6}–{10}^{-8}{\mathrm{c}\mathrm{m}}^{-1}$ were measured with uncertainties $<5\%$, and the absorption coefficients were in agreement with those estimated from the HITRAN database. By tuning the wavelength, a weak absorption line with an absorption coefficient of ${10}^{-9}{\mathrm{cm}}^{-1}$ was measured with a sensitivity of $2\times {10}^{-10}{\mathrm{cm}}^{-1}$. The sensitivity was limited by the residual parasitic variation that appeared in the spectrum.
