TL;DR: The results of this study indicate that an excellent clinical outcome can be achieved with substantial removal of the targeted foreign pigmented matter while potential adverse effects are significantly reduced.
Abstract: The Q-switched ruby laser is currently used in the treatment of amateur and professional decorative tattoos. The present study documents the clinical management and follow-up of 12 subjects with traumatic tattoos treated with the Q-switched ruby laser. The results of this study indicate that an excellent clinical outcome can be achieved with substantial removal of the targeted foreign pigmented matter while potential adverse effects are significantly reduced. Hypopigmentation, which occurred in four patients (33.3 percent), was temporary and resolved spontaneously in all subjects within 6 months of laser exposure. There was no hypertrophic scarring, atrophy, or induration seen in any of the subjects treated with the Q-switched ruby laser. (Plast. Reconstr. Surg. 93: 318, 1994.)

TL;DR: In this article, high-level recombination radiation emitted from silicon was studied, using a Q-switched ruby laser as the source of excitation, and Oscilloscope recordings of the luminescence show very rapid recombination.

TL;DR: In this article, a 4 Hz version of the ruby laser was developed to enhance the rate of cycling of detection and digitizing to match, and the first profiles obtained with the new system are presented.
Abstract: The LIDAR Thomson scattering technique uses the time of flight of a short laser pulse to spatially resolve measurements of electron temperature (Te) and density (ne) in a plasma. The technique was pioneered at JET and the first profiles were obtained in 1986. The initial system used a 3 J, 0.5 Hz, 300 ps ruby laser and microchannel‐plate photomultiplier detectors to make Te and ne profile measurements with ∼10 cm spatial resolution. Since then we have sought to improve both the spatial resolution and frequency of measurement during a JET pulse. It has proved possible to develop a 4 Hz version of the ruby laser and to enhance the rate of cycling of detection and digitizing to match. The main LIDAR system has now been upgraded to 4 Hz and first JET profiles obtained with the new system are presented. For a LIDAR system, the spatial resolution δL along the laser path is given by δL=(c/2)(τ2L+τ2D)1/2, where c is the velocity of light, τL the laser pulse width, and τD the detection system response time.

TL;DR: In this article, a model is presented where only a fraction of the molecules interacts with laser light and the excitation terminates in the S 1 equilibrium level. But the model does not consider the effect of laser action and amplified spontaneous emission.
