SOME MORE ABOUT LASERS

Over the past decade, Edinburgh Instruments1 have proved themselves to be leading technical innovators in the field of infra-red gas lasers. The PL series of lasers produced by Edinburgh Instruments are ideally suited to a large number of applications, in the scientific, industrial and medical fields. The wide tuning range and excellent frequency stability of the PL series make them ideal tools for high resolution molecular spectroscopy (Stark and Zeeman effects, magnetic resonance, double resonance, opto-acoustic spectroscopy, matrix isolation techniques) and solid state spectroscopy (non-linear optics, mixing, spin flip Raman scattering; non-linear absorption and dispersion; optical bistability; magneto-optics; spin resonance). The high stability of any Edinburgh Instruments laser are highly desirable characteristics for infra-red interferometers used in testing distortion and deformation of transmitting materials, lenses and optical surfaces. The PL series can be used in long term studies of atmospheric conditions, they are particularly suitable for pollution detection and monitoring. Laser applications in industry are centred around cutting, drilling, welding and soldering operations. Lasers have many advantages over conventional machine tools. Laser machining is a non-contact process. This means that there is no material distortion, there are no tooling costs and no cutting fluid requirements, which means cleaner work areas and less time required for cleaning finished parts. There is no swarf, since the material is evaporated and can be removed with an extractor fan'. The excellent beam quality ensures the laser output can be focussed to a small diameter spot (less than 50 microns) giving extremely high, localised intensities. Wastage is eliminated by ensuring that a minimum of material is removed during machining operation. A wide range of functions can be performed by the same laser, by using it in any of its three modes of operation: continuous beam, chopped or pulsed.

ЕЩЕ НЕМНОГО О ЛАЗЕРАХ

За последнее десятилетие Edinburgh Instruments зарекомендовали себя как ведущие технические новаторы в области инфракрасных газовых лазеров. Лазеры серии PL производства Edinburgh Instruments идеально подходят для широкого спектра применений в научной, промышленной и медицинской областях. Широкий диапазон настройки и превосходная стабильность частоты серии PL делают их идеальными инструментами для молекулярной спектроскопии высокого разрешения (эффекты Штарка и Зеемана, магнитный резонанс, двойной резонанс, оптоакустическая спектроскопия, методы матричного выделения) и твердотельной спектроскопии (нелинейная оптика, смешивание, спин-флип комбинационное рассеяние; нелинейное поглощение и дисперсия; оптическая бистабильность; магнитооптика; спиновый резонанс).
