Title:
EMITTER BASE ON LASER DIODES
Document Type and Number:
WIPO Patent Application WO/2001/054236
Kind Code:
A2
Abstract:
The invention can be used in telecommunication networks being an important part of optical communication systems, for solid-state laser pumping while developing laser technological equipment, medical equipment, measuring instruments, etc. The essence of the invention lies in an emitter based on a large number of laser diodes the radiation of which is synchronised by the action of at least one external single frequency radiation. Obtainment of an output single-frequency radiation from the multitude of laser diodes is possible at entire spectrum width of an output united beam of optical radiation of a plurality of laser diodes. Said optical radiation does not exceed 15$g(h)m at a wave lengths difference $g(D)$g(l). At the condition that the wave lengths correspond to the centre of gravity of the spectrum of the output united beam and to the centre of gravity of the spectrum of the master single frequency radiation the selected wave lengths difference does not exceed ±15$g(h)m.
