  • 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.
    Type: Grant

  • HIGH-POWER CW FIBER-LASER
    Publication number: 20120230352
    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 minor.

  • High power and high brightness diode-laser array for material processing applications
    Patent number: 7697207
    Abstract: Arrangements for combination and fast-axis alignment of fast-axes of diode-laser beams are disclosed. Alignment arrangements include providing each diode-laser with a corresponding alignable fast-axis collimating lens, providing individually alignable mirrors for steering an re-orienting beams from each diode-laser, and providing single diode-laser slab-modules in which the diode-laser beams can be pre-aligned to a common propagation-axis direction, and in which edges and surfaces of the slabs can be used to align the fast and slow-axes of the beams. Beam combination methods include combination by dichroic elements, polarization-sensitive elements, and optical fiber bundles.
