  • ENCLOSURE FOR MODIFIED OPTICAL FIBER
    Publication number: 20170205579
    Abstract: A mode-stripper for an optical fiber includes a water-cooled enclosure. A portion of an optical fiber to be mode-stripped is modified in a way which allows radiation to leak from cladding of the fiber. The optical fiber extends through the enclosure from a proximal end thereof to a distal end thereof, with the modified portion of the fiber within the enclosure. The fiber is fixedly held in the enclosure at the proximal end thereof and held at the distal end of the enclosure by an elastomeric diaphragm.

  • High-power CW fiber-laser
    Patent number: 9083140
    Abstract: A CW fiber-laser includes a gain fiber having a reflector proximity-coupled to one end, with the other end left uncoated. A laser resonator is defined by the reflector and the uncoated end of the gain-fiber. Pump-radiation from two fast-axis diode-laser bar stacks is combined and focused into the uncoated end of the gain-fiber for energizing the fiber. Laser radiation resulting from the energizing is delivered from the uncoated end of the gain-fiber and separated from the pump-radiation by a dichroic mirror.
    Type: Grant

  • High-power CW fiber-laser
    Patent number: 9014220
    Abstract: A CW ytterbium-doped fiber-laser includes a gain-fiber having a reflector proximity-coupled to one end, with the other end left uncoated. A laser resonator is defined by the reflector and the uncoated end of the gain-fiber. Pump-radiation from fast-axis diode-laser bar-stacks emitting at 915 nm and 976 nm is combined and focused into the uncoated end of the gain-fiber for energizing the fiber. Laser radiation resulting from the energizing is delivered from the uncoated end of the gain-fiber and separated from the pump-radiation by a dichroic mirror.

A laser resonator is defined by the reflector and the uncoated end of the gain-fiber. Pump-radiation from two fast-axis diode-laser bar stacks is combined and focused into the uncoated end of the gain-fiber for energizing the fiber. Laser radiation resulting from the energizing is delivered from the uncoated end of the gain-fiber and separated from the pump-radiation by a dichroic minor.
