Multi-wavelength raman laser |
| abstract |
A multi-wavelength Raman laser comprising a Raman fiber forming part of an opticalnring, preferably most parts of which are formed by optical fiber. The ring includes a periodicnfilter selectively transmitting optical power at a number of equally spaced wavelengthsncorresponding to the wavelengths of the laser output. Radiation at the signal wavelengthsnpropagating in one direction on the ring is tapped onto an output fiber. An optical isolator isnformed either in the ring or fiber tapped into the ring to suppress radiation propagating in thenreverse direction on the ring. A frequency shifter may be inserted into the loop to preventnpower from concentrating in a single mode, thereby allowing wide band lasing. A band passnfilter may be inserted into the loop to restrict the lasing band. |
