Patent number: 6195369Abstract: A highly stable soliton source uses a bulk Er/Yb glass laser which operates in two longitudinal modes of the laser cavity with substantially identical amplitudes to generate beat modulation. The beat modulation is then passed through a pulse compression fiber which compresses the beat modulation into a train of soliton pulses. Because the beat modulation is between two modes of the same laser cavity, the soliton pulse train generated is highly stable with low timing jitter.Type: GrantFiled: October 24, 1997Date of Patent: February 27, 2001Assignee: Scientific-Atlanta, Inc.Inventors: Prem Kumar, Donald L.

Patent number: 6088153Abstract: A multi-functional optical isolator that couples radiation from a plurality of input fibers to a plurality of output fibers such that an optical beam emitted from any particular input fiber is transmitted only to its corresponding output fiber. Additionally, an optical beam emitted in the reverse direction from any output fiber is not transmitted back into any of the input or output fibers. The multi-functional optical isolator includes a first focusing lens that collimates the optical radiation emitted from the input fibers and causes them to pass through an optical isolator. The optical isolator has polarizing elements and a magneto-optic polarization rotator. A second focusing lens focuses the optical beams into the output fibers such that the optical radiation from each input fiber is coupled to its corresponding output fiber. Additional off-axis optical elements at other wavelengths may be used for providing bulk-optic coupling of a pump light into a single-mode or multi-mode core of a doped fiber.Type: GrantFiled: June 4, 1998Date of Patent: July 11, 2000Assignee: Scientific-Atlanta, Inc.Inventors: Douglas W.

Patent number: 4884277Abstract: 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.Type: GrantFiled: June 16, 1988Date of Patent: November 28, 1989Assignee: Amoco CorporationInventors: Douglas A.

Patent number: 4841528Abstract: Higher efficiency in cavity dumping and frequency doubling in a laser used to produce modulated output beam pulses is achieved by deflecting light out of the resonant cavity to a third mirror through a frequency doubler using an electro-optic modulator and a polarizing beamsplitter in the resonant cavity, or using just an acousto-optic modulator to deflect light out of the laser cavity in response to a control signal (electric or acoustic). The frequency doubler in front of the third mirror rotates the frequency doubled light so that it will pass out of the laser cavity through the polarizing beamsplitter, while undoubled frequency light is reflected by the polarizing beamsplitter back into the gain medium of the laser. In the case of using a type-II frequency doubler, a dichroic beamsplitter deflects out the frequency doubled light and passes the undoubled frequency light to the polarizing beamsplitter for return to the laser gain medium.Type: GrantFiled: September 6, 1988Date of Patent: June 20, 1989Assignee: California Institute of TechnologyInventors: Donald L. Sipes, Jr., Deborah L. Robinson

Patent number: RE34729Abstract: An optically pumped single mode laser, e.g. Nd:YAG crystal (20) with planoconcave mirrors is increased in efficiency by an order of magnitude to about 8% by optics (25, 27) for focusing the high power multimode output of laser diode arrays (21, 22) into the mode volume (20') of the laser medium (20). A plurality of these optically pumped single mode lasers (1-4) may be cascaded in a ring with dichroci mirrors (M.sub.1 -M.sub.4) at the corners for coupling in the laser diode arrays, each having its own means for spatially tailoring its beam to concentrate pump distribution inside the lasing mode volume of the medium. An InGaAlAs pump diode (30) with its wavelength of the same as a lasing medium makes the ring unidirectional.The questions raised in reexamination request No. 90/002,473, filed Oct. 10, 1991, have been considered and the results thereof are reflected in this reissue patent which constitutes the reexamination certificate required by 35 U.S.C. 307 as provided in 37 CFR 1,570(e).Type: GrantFiled: November 12, 1991Date of Patent: September 13, 1994Assignee: California Institute of TechnologyInventor: Donald L.
