TL;DR: In this article, a laser system using bleachable filter Q-switching has been used to obtain simultaneous "giant pulses" from five ruby laser oscillators, but the beams from the different oscillators were found to be phase-locked.
Abstract: A laser system using bleachable‐filter Q‐switching has enabled us to obtain simultaneous ``giant pulses'' from five ruby laser oscillators. The beams from the different oscillators were found to be phase‐locked; the beam divergence was limited by the initial ruby quality. Two other systems for obtaining simultaneous giant pulses were investigated. One involved using the giant pulse from one oscillator to switch the bleachable cells in other oscillators; the other consisted of feeding the giant pulse from one oscillator into a branching chain of amplifiers. These latter systems proved less desirable for expansion to a large number of laser rods.

TL;DR: In this paper, a nonsubstitutional alloy of 7 at. % Cr implanted in single-crystal aluminum has been irradiated with Q-switched ruby laser pulses up to 6 J/cm2.
Abstract: A nonsubstitutional alloy of 7 at. % Cr implanted in single‐crystal aluminum has been irradiated with Q‐switched ruby laser pulses up to 6 J/cm2. Liquid phase epitaxy, resulting in enhanced substitutionality without any Cr redistribution, is observed up to 2 J/cm2 for a laser pulse duration of 25 ns. At higher energy densities and with shorter pulses, 12‐nsec duration, convection effects are observed to inhibit liquid phase epitaxy. The surface reflectance appears to reduce due to high implantation dose.

TL;DR: In this article, four individually Q-switched laser cavities have been established sharing a common ruby laser rod, and single giant pulses have been emitted with a time duration of ≈ 30 ns (half width) and energies of 0.16 J from each cavity apertured by a 2.54mm-diameter hole.
Abstract: Four individually Q -switched laser cavities have been established sharing a common ruby laser rod. Single giant pulses have been emitted with a time duration of ≈ 30 ns (half-width) and energies of 0.16 J from each cavity apertured by a 2.54-mm-diameter hole. The spacing of the pulses was continuously variable in time from 0 to 1.25 ms plus or minus a jitter time of approximately 13 ns. This multiple-cavity laser light source can be used as a stroboscopic illuminator for photographic or holographic recording of fast events.

TL;DR: In this paper, the characteristics of a quasi−cw single-mode ruby laser which is pumped by an argon laser are described, with particular emphasis on aspects which govern the linewidth.
Abstract: The characteristics of a quasi−cw single−mode ruby laser which is pumped by an argon laser are described. Particular emphasis is given to aspects which govern the linewidth. By heterodyning two independent lasers, linewidths as narrow as 0.5 MHz have been observed, averaged over a few seconds.

TL;DR: In this paper, a single-transverse-mode, single-longitudinal-mode ruby laser with a pulse length of 6-12 ns (intensity half-height full width) was assembled.
Abstract: We have assembled a single-transverse-mode, single-longitudinal-mode ruby laser with a pulse length of ~6–12 ns (intensity half-height full width). Pulsed holograms have been made by use of this laser. The laser carrier-frequency shift (or chirp) has been measured and is found to be the limiting factor on the depth of field of the hologram. In order to demonstrate this, we present a quantitative measurement of hologram quality.
