Record 6 2012-04-24

English

Subject field(s)
  • Lasers and Masers
  • Air Navigation Aids
  • Surgical Instruments
CONT

Continuous-Wave Lasers. ... Often it is desirable to have a continuous laser beam rather than a series of pulses, in which case pumping energy must be put in continuously to maintain a population inversion.

CONT

Continuous-wave lasers have been employed as a "light knife," that is a surgical cutting and coagulation tool.

CONT

[The laser airspeed indicator] employs a continuous-wave laser focused on a specific plane at the required distance ahead of the aircraft.

OBS

Although "continuously operating laser" is found in at least two sources, it seems more of an explanation of the function of a laser rather than a definite term.

French

Domaine(s)
  • Masers et lasers
  • Aides à la navigation aérienne
  • Instruments chirurgicaux
DEF

Oscillateur dont la puissance ne varie pas au cours du temps.

CONT

Un laser continu peut servir comme une sorte de scalpel lumineux incisant les tissus par brûlure.

CONT

[L'indicateur de vitesse à laser] repose sur l'emploi d'un faisceau laser à onde entretenue dont le foyer est fixé à la distance voulue en avant de l'avion.

Spanish

Campo(s) temático(s)
  • Láser y máser
  • Ayuda para la navegación aérea
  • Instrumental quirúrgico
DEF

Láser constituido por una envuelta de cuarzo rellena de una mezcla de helio y neón a baja presión con espejos de Breuster en sus extremos y un sistema óptico exterior.

OBS

[Este dispositivo produce un] foco de luz coherente [que emplea] un sólido cristalino (por ejemplo un rubí) o un tubo de descarga de gases en el cual son inyectados átomos simultáneamente en estados excitados por una descarga de luz incoherente. Estos vuelven a su estado estable con emisión de un impulso de luz cuyo flujo de energía puede ser de 10 mw/cm².

OBS

El primer láser de funcionamiento continuo fue el láser de gas producido por Bell Telephone Laboratory (1960) en el cual se aplicaba una descarga de baja energía, en una mezcla de gases helio y neón, para producir un haz muy definido e intenso de radiaciones infrarrojas.

Record 7 1996-07-15

English

Subject field(s)
  • Analytical Chemistry
CONT

A special form of fluorometry uses a laser source and provides for extremely sensitive detection of fluorescing solutes. ... This approach holds great promise for the future, particularly when instruments with variable-wavelength laser sources become commercially available.
