With the publication of this second supplement to the Continuing Bibliography entitled "Lasers and Masers", NASA SP-7009, the National Aeronautics and Space Administration continues its program of distributing selected references to reports and articles on aerospace subjects that are currently receiving intensive study. All references have been announced in either Scientific and Technical Aerospace Reports (STAR), International Aerospace Abstracts (IAA), or the NASA Continuing Bibliography Aerospace Medicine and Biology (NASA SP-7011 and its supplements). They are assembled in this bibliography to provide a reliable and convenient source of information for use by scientists and engineers who require this kind of specialized compilation. In order to assure that the distribution of this information is sustained, Continuing Bibliographies are updated periodically through the publication of supplements which can be appended to the original issue.

The scope of coverage of this supplement, NASA SP-7009 (02), is extensive, and references to all major studies associated with the research on, and development of, lasers and masers are included. Special emphasis is given to laser and maser applications as they relate to ranging and communications systems, astronomy and optics, and metalworking. Pertinent references to fundamental studies devoted to the physical and electronic properties of lasers and masers, as well as their function and performance, will also be found in this collection.

Each entry in the bibliography consists of a citation and an abstract. The listing of entries is arranged in two major groups. Report literature references are contained in the first group and are arranged according to their date of announcement in STAR. The second group includes published literature references, arranged according to their date of announcement in IAA, or in Aerospace Medicine and Biology. All reports and articles cited were introduced into the NASA information system during the period February, 1966-April, 1967.

A subject index and a personal author index are included. These indexes use the Notation of Content (NOC), a one-sentence description of the contents of a document, rather than the title, to aid the user in locating pertinent entries.

basis of these data for a 0.02 M europium complex in a 5 cm tube. Additional compounds prepared include: triethyl phosphate complexes of Sm Clz. NdC1z. PrCiz. and Tb Ciz. which resemble the Euclz complexes; also EuCl3 complexes with triphenyl phosphate, urea, thiourea, dimethyl sulfoxide, dimethyl formamide, dimethyl acetamide, and tetra methylurea. Fluorescence in the complexes having C=O and S=O ligands is enhanced over that in aqueous Eu solutions, but not as much as in P=O complexes. The formation of precipitates from heated EuCiz-alkyl phosphate complexes was further studied and a formula for the precipitate is proposed.

Experiments to determine the relative intensity of light scattered at various angles from several materials were performed. Various target materials were mounted on an optical bench and illuminated by a Spectra Physics 116 gas laser. The targets were rotated through various angles with respect to the optical bench, and the distance between the detector and target was varied to record a constant voltage reading on a 555 oscilloscope. Different graphs showing isointensity lines for various angles of incidence as well as graphs showing the percent of intensity reflected as a function of distance were then plotted.

Experimental evidence is presented to suggest that scat. tering mechanisms in a medium can produce inhomogeneities or filamentary structure in an initially homogeneous laser beam. It is these hot filaments which are responsible for the many anomalous effects previously observed

Studies were made of europium complexes of hexamethyl phosphoramide triethyl phosphate, and tri-n-butyl phosphate. which are promising direct-excitation liquid laser materials. An overall quantum efficiency of 0.5 for fluorescence was measured. It was found that complex formation is essentially com.. plete when the Eu concentration is below 0.2 M even when hydrated Eu salts are used. The excess of 5Do states required for laser action was calculated. A laser threshold of 6.3 watts/ cm3 per A interval of the absorption band is calculated on the
