Book Synopsis Atmospheric Attenuation of HF and DF Laser Radiation by : Robert A. McClatchey
Download or read book Atmospheric Attenuation of HF and DF Laser Radiation written by Robert A. McClatchey and published by . This book was released on 1972 with total page 148 pages. 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.

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).

Book excerpt: A survey of the atmospheric attenuation properties of usually applied laser (GaAs, YAG, HF, DF, and CO2) is given. From an analysis of the results of absorption and scattering processes produced by the interaction of atmospheric medium and laser radiation, comprehensive comparisons of transmission property are performed. Lastly, the optimum applied environment of every laser is indicated.

Download or read book Atmospheric Attenuation of CO Laser Radiation written by R. A. McClatchey and published by . This book was released on 1971 with total page 122 pages. 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).

Available in PDF, EPUB and Kindle. Book excerpt: Calculated atmospheric absorption coefficients are reported at 62 HF, 104 DF, and 6 Iodine laser line frequencies. Results are tabulated at 16 atmospheric layers for 50% relative humidity conditions ranging from sea-level to 15 km altitude, Results of measurements made on seven HF lines at WSMSR/ASL agree well with these results. Documentation is provided describing the data base, the laser line frequencies, and the atmospheric model. Net absorption coefficients are reported for several representative laser output power-spectral distributions.

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.

Book Synopsis Absorption of Deuterium Fluoride Laser Radiation by the Atmosphere by : Frank Schriver Mills
Download or read book Absorption of Deuterium Fluoride Laser Radiation by the Atmosphere written by Frank Schriver Mills and published by . This book was released on 1975 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Absorption of deuterium fluoride (DF) laser radiation by atmospheric gases was measured for five absorbers and 8 laser lines using a single frequency, pulsed DF laser and a large multipass absorption cell. N2O, CH4, C2O, HDO and H2O absorption was investigated for the 2-1 P(6), P(7), P(8), P(10), and P(11) lines and the 3-2 P(6), P(7), and P(8) lines of the DF laser. For the mid-latitude summer sea level atmospheric model (14.3 torr H20, 1.6 ppm CH4, 0.28 ppm N2O, temperature 296K, total pressure 760 torr) the total molecular absorption coefficients are between 0.318 per km and 0.116 per km corresponding to a transmittance over a 10 km path of from 31 to 73 percent. Assuming the mid-latitude summer model atmosphere, the water vapor continuum absorption coefficient for the eight lines is approximately 0.02 per km. The measured HDO absorption coefficients vary from 0.006 per km to 0.095 per km for the lines studied and the N2O absorption coefficients vary from .002 per km to 0.45 per km. The CH4 absorption coefficients were found to be on the order of 0.0001 or 0.0001 per km. The accuracy of the measured absorption coefficients is + or -5%. Measurements of H2O absorption at 24 C with 14.3 torr H2O and 760 torr total pressure confirm the water continuum absorption coefficients obtained by extrapolating the high temperature measurements.
