TL;DR: The results are discussed and the advantages and disadvantages of the ruby laser as a source of energy to coagulate the choroid and retina are discussed.
Abstract: Preliminary reports1-* established that retinal coagulations could be effected using a laser source and suggested the desirability of its use clinically. Studies of photocoagulation at the Retina Foundation include an evaluation of laser as a retinal coagulator, on the basis of 9000 coagulations in pigmented rabbits and a limited number of humans. This report is a discussion of our results and of the advantages and disadvantages of the ruby laser as a source of energy to coagulate the choroid and retina.

TL;DR: In this paper, the cross section of a light beam diffusor, which is situated between a laser source and an impurity-implanted substrate, facing the substrate is made to be equal with the area of a chip.
Abstract: PURPOSE:To irradiate a laser beam only to a desired area to obtain uniform annealing by a method wherein the cross section of a tip of a light beam diffusor, which is situated between a laser source and an impurity-implanted substrate, facing the substrate is made to be equal with the area of a chip. CONSTITUTION:In a laser annealing process using, for example, a ruby laser, a light beam diffusor 1 made from a quartz rod is situated between the laser source and a substrate 12. An input end 2 of the light beam diffusor 1 is slightly larger than the laser beam diameter (for example, by approx. 10mm.), and its surface is roughly ground. An output end 3 of the diffusor 1 is shaped similarly with the shape of a chip 13 (for example, a rectangle of 5mm. square) and mirror polished. Further, the side is also mirror polished. With this structure, a scattered, uniformed layer beam can be irradiated onto the chip 13, accordingly, an yield in a laser annealing process can be enhanced, and also reduction of working process can be attained.

TL;DR: In this paper, a numerical simulation of phase transitions induced by nanosecond pulsed radiation from a ruby laser in CdTe has been carried out, and it is shown that evaporation of Cd atoms results in cooling of the surface; consequently, a nonmonotonic profile of the temperature field is formed, with the maximum temperature being attained in the bulk of the semiconductor at a distance of about 10-30 nm from the surface.
Abstract: A numerical simulation of the dynamics of phase transitions induced by nanosecond pulsed radiation from a ruby laser in CdTe has been carried out. It is shown that evaporation of Cd atoms results in cooling of the surface; consequently, a nonmonotonic profile of the temperature field is formed, with the maximum temperature being attained in the bulk of the semiconductor at a distance of about 10–30 nm from the surface. At radiation energy densities above the threshold, the molten state formed under the surface extends both to the surface and into the depth of the semiconductor. Crystallization also proceeds in two directions, namely, from the surface into the depth of the samples due to the growth of nucleation centers in the melt, which is highly depleted in Cd atoms under the conditions of intense heat removal, and from the substrate to the surface due to epitaxial growth.
