Web11 apr. 2024 · Recently, an experimental study of a simple and widely tunable fibre laser multiwavelength sources with triple frequency shift spacing was suggested by Al-Mashhadani et al. ( 2024 a). Up to six triple Stokes lines tuned over a wavelength range of 50 nm from 1530 to 1580 nm were generated at a pump power value of 220 mW. Web12 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 …
