Techniques of recording. The pupils are well dilated and the patient sits in front of the camera with one arm outstretched. Twenty-five milligrams of ICG [indocyanine green] dye is dissolved in 0. 5 ml [millilitres] of the manufacturers aqueous solvent and given intravenously as a bolus followed by a 5 ml physiological saline solution flush. The flush eliminates the need for image intensification. Preferably 10 images should be obtained starting immediately after injection and lasting the first 30 seconds.... The ICG angiograms may be recorded either by using a modified conventional fundus camera or scanning laser ophthalmoscope.  2, record 1, English, - indocyanine%20green%20angiogram

Genesis of the scanning laser ophthalmoscope. ... In the scanning device, the illumination is incident on a small spot of the fundus for a short time period, the illumination beam is displaced to the adjacent small spot, and this continues until the field of view of the fundus is covered. Simultaneously, with the spot of illumination, the scattered light is detected; the accumulation of all of the light from all of the illuminated spots forms the image of the fundus as seen on the display of the scanning laser ophthalmoscope.  7, record 2, English, - scanning%20laser%20ophthalmoscope

Scanning laser ophthalmoscopes produce high-contrast images even through narrow pupils. Using various color lasers, this method can [allow visualization of] particular structures of the retina noninvasively, i. e., without injection of a contrast agent. These structures include nerve fibers, drusen, nevi, and autofluorescent material.  8, record 2, English, - scanning%20laser%20ophthalmoscope

Principe de fonctionnement d'une diode laser. Une diode laser se compose d'un tube semi-conducteur, d'une bobine d'excitation, d'un miroir total et d'un miroir partiel. À l'aide d'un courant électrique circulant dans la bobine, on élève le niveau énergétique des couches d'électrons des atomes des molécules du semi-conducteur. Lorsque le niveau énergétique retombe, cette chute se traduit par l'émission de photons. Lorsque ces photons rencontrent d'autres atomes, ils provoquent l'élévation du niveau énergétique, et ainsi de suite. Au bout d'un certain temps, on obtient un ensemble de rayons parallèles les uns aux autres dont une partie parvient à s'échapper par le miroir semi-réfléchissant. On obtient en sortie un faisceau lumineux très dense (dangereux pour les yeux, même si il est invisible) appelé laser.  4, record 9, French, - diode%20laser

Ce schéma se prête à l'emploi de tous les types de cibles et de faisceaux d'énergie; il pose néanmoins le problème de la restauration, entre deux impulsions, de la qualité de l'atmosphère de la chambre.

It is a technique to shrink and harden the disk by application of the Holmium laser at low (5 watts) energy levels. Discectomy is done with micro-curettes and forceps, automated discectome, Holmium side-firing laser at ablative energy levels for discectomy, and non-ablative levels for laser thermodiskoplasty, all under C- arm and endoscopic control.  1, record 12, English, - Holmium%20side%2Dfiring%20laser

Endoscopic Facet-Joint Surgery(EFJS). In those cases where facet joint injection has temporarily relieved the symptoms and they have been incompletely alleviated by cryogenic rhizotomy, then endoscopic visualisation can be used to identify the nerves and especially the anterior nerves. These can be divided by laser sidefire probes and Holmium ablation. The joints can be opened and the rough surfaces can be sculptured again using Holmium sidefiring laser probes.  2, record 12, English, - Holmium%20side%2Dfiring%20laser

The heterostructure laser. Heterostructures have been crucially important for the development of semiconductor lasers.... Alferov was the first to succeed in producing a lattice-adapted heterostructure(AIGaAs/GaAs, 1969) with clear borders between the layers. Alferov's research team succeeded in rapidly developing many types of components built up of heterostructures, including the injection laser which Alferov patented in 1963. A technological breakthrough occurred around 1970 when heterostructure lasers became able to work continuously at room temperatures. These properties have, for example, made fibre-optic communications practically possible.  2, record 13, English, - heterostructure

[...] la durée de vie utile d'un laser à semi-conducteur est plus longue quand on limite la quantité d'électricité qui le traverse. Il existe plusieurs façons de limiter le courant électrique. On peut, par exemple, introduire d'autres éléments chimiques dans le cristal, de sorte que la couche active du laser soit située entre des matériaux dont la bande interdite est particulièrement large. On obtient ainsi une "hétérostructure" dont les barrières d'énergie internes empêchent la diffusion des porteurs de charge hors de la région active.
