Patent ID: 7738178

Claim:
A laser assembly for coupling laser light into at least one optical fiber, the laser assembly comprising: a plurality of laser light sources disposed spaced from a light entrance surface of the at least one optical fiber, said plurality of laser light sources including at least one group of first laser light sources and at least one group of second laser light sources; an aperture suitable for spatially confining the laser light emitted during operation of said laser light sources before being coupled into the at least one optical fiber; a coupling device for coupling the laser light during operation of said first and second laser light sources before the laser light enters into the at least one optical fiber; and at least one phase delay element associated with at least one of said groups of said first and second laser light sources; said coupling device having at least one polarization coupling device for coupling the laser light emitted by said group of first laser light sources with the laser light emitted by said group of second laser light sources; and said coupling device having at least one beam deflection device for deflecting the laser light emitted by at least one of said groups of first and second laser light sources in a direction of said polarization coupling device.
