Fast-switching multi-wavelength laser
Patent
·
OSTI ID:6571914
The laser comprises an amplifying medium placed between a first reflector and a second dispersive reflector, and a rotating wheel adapted to carry a plurality of optical deflector elements interposed between the amplifying medium and the second dispersive reflector. A light beam having a certain incidence only in respect of a predetermined wavelength which is dependent on the incidence is reflected backwards from the second dispersive reflector. The optical reflector elements are placed periodically in the path of the light beam so as to produce a sequential modification in the incidence of the light beam emerging from the amplifying medium and to give the incidence a number of different values corresponding to the desired number of wavelengths.
