Notes: Abstract An analysis is made of the application a generalized method of eigenmodes, which is used in steady-state diffraction problems to the theory of lasers. In the study of open laser cavities the use of this method makes it possible to avoid difficulties associated with the exponential growth of the field at infinity. The generalized method developed previously for solving steady-state diffraction problems is extended to the case of non-steady-state narrow-band processes to construct in the ordinary way the equations describing the operation of the laser. The only difference is that the field is expanded in the eigenfunctions that are orthogonal in the region occupied by the active medium. This eliminates the difficulties associated with the behavior of the mode field at infinity. In addition, in a number of cases the generalized eigenfunctions (modes) correspond considerably better to the field distribution in the operating laser.

Notes: Abstract A photoelectric method is described for the determination of the isotopic composition of hydrogen-tritium mixtures using the atomic spectrum excited in a high frequency discharge. Sealed discharge tubes with a ballast volume are used to eliminate errors caused by the adsorption of hydrogen under the action of the discharge. The standard deviation of a single determination is 1.5–2. 0% of the smaller concentration. An analysis takes 30 min, and the sample may be used for its original purpose.

Notes: Abstract Sealed hollow-cathode lamps containing the metals (Al, Bi, Ca, Cd, Co, Cr, Cu, Fe, Mg, Mo, Ni, Pb, Sb, Sn, Ti, and Zn) have been examined for the relation of resonance-line strength and width to nature and pressure of the inert gas and also to discharge current. The relations are found to be generally applicable to hollow cathodes of most metals. The inherent noise level of the lamps does not exceed 0.1%.
