TL;DR: In this article, the authors measured the Fabry-Perot mode spacings of Raman oscillators and found that substantial mode pulling was occurring, interpreted according to mode-pulling theory.
Abstract: Stimulated Raman scattering has been observed in quartz at low temperatures in which the 467 cm−1 Stokes line is split into two or more sharp components. The quartz samples, which were in the form of resonant cavities, behaved as Raman oscillators pumped by a ruby laser. Measurement of the Fabry—Perot mode spacings of the oscillators showed that substantial mode pulling was occurring. This was interpreted according to mode‐pulling theory.

TL;DR: In this article, the quantum flux G corresponding to the breakdown threshold E field is given by an equation which is approximately of the form ln 44 = ln[δt/A(G/ω)] - B(ω/G)1/2 where Δt and ω are the laser pulse length and frequency, and A and B are constants.
Abstract: Solving the quantum-kinetic equation for electrons interacting with deuterium molecules and a 1.8-eV photon field, we have made time-dependent calculations of the breakdown of deuterium gas by a ruby laser. We find that the quantum flux G corresponding to the breakdown threshold E field is given by an equation which is approximately of the form ln 44 = ln[δt/A(G/ω)] - B(ω/G)1/2where Δt and ω are the laser pulse length and frequency, and A and B are constants. The field strength thresholds which emerge from these calculations are compared with available experimental data, and good agreement is obtained.

TL;DR: In this paper, a LiIO3 crystal, placed inside a doubly resonant oscillator, was pumped with the second harmonic of a Q•switched ruby laser, and a 0.415 to 2.1μm tuning range for both signal and idler was obtained.
Abstract: A LiIO3 crystal, placed inside a doubly resonant oscillator, was pumped with the second harmonic of a Q‐switched ruby laser. A 0.415‐ to 2.1‐μm tuning range for both signal and idler was obtained. The conversion efficiency from pump to signal power amounts to 8%. The peak power of the signal radiation was 10 kW and the pulse duration was 5 nsec.

TL;DR: In this article, a two-wavelength surface contouring system based on electronic speckle pattern interferometry (ESPI) with a pulsed ruby laser is reported, where two states of the test object were recorded at different wavelengths of the laser.
Abstract: A two-wavelength surface contouring system based on electronic speckle pattern interferometry (ESPI) with a pulsed ruby laser is reported. Two states of the test object were recorded at different wavelengths of the laser. The wavelength change was controlled by altering the temperature of the output etalon. The phase information of the surface contour can be obtained by using either the sinusoid fitting method or the Fourier transform method. Contour intervals of about 14 mm and 7 mm are available.
