We present first results on the continuous-wave absorption spectroscopy on the A 2Σ+ ← X 2Π1/2 transition of the γ00-band in nitric oxide. The measurement is done at room temperature. The production of the necessary glass cells as well as technical challenges of the employed laser system are explained. To prove the validity of the results the needed theory is analyzed. For putting the results into perspective pulsed absorption spectroscopy was performed on the same transition at much lower temperature allowing for comparison and yielding important insights on the advantages of continuous- wave spectroscopy. The results are classed with the overall goal of building a trace-gas sensor for nitric oxide.
