Book excerpt: Atmospheric attenuation was studied for 102 different CO laser lines in the region 1720/cm to 2080/cm. The purpose was to determine how the various atmospheric constituents affected the transmittance of these lines. Six model atmospheres, two aerosol models, and the molecular absorption parameters for the lines of water vapor, O3, CO2, N2O, and CO were included. The calculations were done on a CDC 6600 computer. Transmittance curves for the Midlatitude Winter-'hazy' model, power-on-target curves for six different multi-line CO lasers, and tables of absorption/scattering coefficients for 69 different CO laser lines were computed. (Modified author abstract).

Available in PDF, EPUB and Kindle. Book excerpt: With the development of the CO laser having emission lines in the range from 1200/cm to greater than 2000/cm, it is of importance to establish which of the more than 200 lines can be transmitted through a variety of atmospheric paths. The spectral region of CO emission spans a very important water vapor absorption band and, in addition, there is absorption by CO2, O3, N2O and CH4. Absorption lines associated with all of these molecules were included in the calculation of synthetic spectra covering the region of CO emission. After limiting the number of CO emission lines to be considered in detail according to a criterion based on atmospheric attenuation, a series of tables was constructed providing quantitative attenuation information for each of 88 laser lines and for 10 different atmospheric models. Data based on two different aerosol scattering models are included in these tables. (Author).

Download or read book Atmospheric Transmittance 7 30 Micrometers written by R. A. McClatchey and published by . This book was released on 1972 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: High resolution transmittance curves are presented for the spectral region 320-1400 wave numbers. These spectra are useful as a guide for selecting laser wavelengths for atmospheric propagation studies in this spectral region. In addition, this report provides specific information concerning the attenuation coefficients of 41 CO2 rotational laser lines in the 10.4 micrometer band system (v3 to v1). Charts for predicting the atmospheric attenuation of the CO2 laser lines are provided for each of five climatological model atmospheres and two haze models. The current report extends the work presented in two earlier reports on (1) CO laser attenuation in the 1400-2120/cm−1 (4.72-7. 14 micrometers) region: AFCRL-71-0370 and (2) HF and DF laser attenuation in the 2120-3740/cm (2.67-4.72 micrometers) region: AFCRL-72-0312. This report, when combined with the two previous reports described above, provides synthetic spectra for the entire region from 2.67-31.25 micrometers.

This book was released on 1974 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: High resolution atmospheric transmittance curves are presented for the spectral region 320 to 13,200/cm (0.7576 to 31.25 micrometers). These spectra are useful as a guide for selecting laser wavelengths for atmospheric propagation studies in this spectral region. In addition, this report provides attenuation coefficients for those lines of the CO, HF, DF, and CO2 laser systems which suffer the least atmospheric attenuation. A new aerosol model is introduced here, taking into account recent measurements of the complex index of refraction of aerosol particles. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: With the development of HF and DF lasers having emission lines in the range from 2800 to 3700/cm−1 (HF) and 2000 to 2750/cm−1 (DF), it is of importance to establish which of the more than 100 lines can be transmitted through a variety of atmospheric paths. The spectral region of HF emission spans a very important water vapor absorption band and, in addition, there is strong absorption by CO2 and weaker absorption by ozone and methane. The spectral region of DF emission covers the very strong 4.3 micrometer CO2 absorption band and weaker absorption by N2O and HDO at higher frequencies (low DF vibrational transitions). There is some weak ozone absorption also in the region of DF emission. Absorption lines associated with all of these molecules were included in the calculation of synthetic spectra covering the region of HF and DF emission. After limiting the number of emission lines to be considered in detail according to a criterion based on atmospheric attenuation, a series of tables was constructed providing quantitative attenuation information for each of 97 laser lines and for 10 different atmospheric models. Data based on two different aerosol scattering models are included in these tables.
