  • 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.

  • Optical fiber with irregularities at cladding boundary
    Patent number: 6411762
    Abstract: An optical fiber (10) made with a central core (12), a first cladding layer (16), and a second cladding layer (18) having a series of perturbations or irregularities formed into the otherwise generally circular outer boundary of the first cladding layer (16). The irregularities in the first cladding layer (16) interrupt the propagation of skew rays and encourage coupling into the core (12).

  • Frequency conversion of optical radiation
    Patent number: 4884277
    Abstract: An intracavity frequency-modified laser of improved amplitude stability is obtained through the use of a plurality of nonlinear optical crystals within the laser cavity. Extremely low noise operation of such a multiple crystal laser is achieved by measuring the noise in its output radiation as a function of the temperature of its optical cavity and maintaining the cavity temperature at a value that results in low noise production during subsequent operation.
