NettetLaser linewidths: tutorial. In this tutorial, the physical origins and mathematical analyses of laser linewidths are reviewed. The semi-classical model is based on an equation for the light-mode amplitude that includes random source terms, one term for each process that affects the amplitude (stimulated and spontaneous emission, stimulated ... Nettet12. apr. 2024 · Using Tunable Diode Laser Absorption Spectroscopy (TDLAS), 82 CH3I overtone absorption lines were detected for the first time in the range between 11,660 and 11,840 cm−1 (844–857 nm), with strengths estimated around 10−27–10−26 cm/molecule. The lines were measured utilizing commercial heterostructure F–P type diode …
