Rare-Earth Doped Phosphate-Glass Single-Mode Fiber Lasers

View page
US Patent:
6816514, Nov 9, 2004
Filed:
Jan 24, 2002
Appl. No.:
10/056830
Inventors:
Shibin Jiang - Tucson AZ
Christine P. Spiegelberg - Tucson AZ
Assignee:
NP Photonics, Inc. - Tucson AZ
International Classification:
H01S 330
US Classification:
372 6, 372 99, 372 92, 372102, 385 37
Abstract:
A compact low-cost continuous single-mode fiber laser delivers output powers in excess of 50 mW over the C-band (1530 nm-1565 nm). The phosphate glass fiber supports the high doping concentrations of erbium and ytterbium (Er:Yb) without self-pulsation that are required to provide sufficient gain per centimeter needed to achieve high power in the ultra short cavity lengths necessary to support single-mode lasers. The use of fiber drawing technology provides a lower cost solution than either combined solution doping/MCVD fiber fabrication or waveguide fabrication. The ability to multi-mode clad pump the fiber further reduces cost, which is critical to the successful deployment of fiber lasers in the burgeoning metro markets.

High-Power Narrow-Linewidth Single-Frequency Laser

View page
US Patent:
6940877, Sep 6, 2005
Filed:
May 30, 2003
Appl. No.:
10/448870
Inventors:
Yongdan Hu - Tucson AZ, US
Christine Spiegelberg - Tucson AZ, US
Jihong Geng - Tucson AZ, US
Assignee:
NP Photonics, Inc. - Tucson AZ
International Classification:
H01S003/30
H01S003/13
US Classification:
372 6, 372 32
Abstract:
A narrow-linewidth high-power single-frequency laser is realized by pumping a laser cavity with a pair of polarized single-mode pump lasers that are driven below their respective “micro-kink” regions and combined with a polarized beam combiner. The pump lasers emit at the same wavelength and include a length of polarization-maintaining (PM) fiber to maintain the polarization of the respective pumps. The laser cavity is selected from microchip, fiber and waveguide devices and is provided with optical feedback. This laser is capable of producing a stable high-power single-mode signal with a very narrow linewidth, e. g. less than 10 kHz and preferably less than 3 kHz.

Erbium-Doped Phosphate-Glass Tunable Single-Mode Fiber Laser Using A Tunable Fabry-Perot Filter

View page
US Patent:
6965620, Nov 15, 2005
Filed:
Mar 10, 2003
Appl. No.:
10/384813
Inventors:
Christine P. Spiegelberg - Tucson AZ, US
Jihong Geng - Tucson AZ, US
Yushi Kaneda - Tucson AZ, US

Assignee:
NP Photonics, Inc. - Tucson AZ
International Classification:
H01S003/00
US Classification:
372 6, 372 92, 372 99, 372102
Abstract:
A short laser cavity (up to 30 cm in length) comprising a free-space tunable MEMS Fabry-Perot filter, a collimating lens and a section of erbium-doped phosphate gain fiber (2-25 cm) is formed between a pair of broadband reflectors. The cavity is optically pumped to excite the erbium ions and provide gain, which establishes an initial longitudinal mode structure that spans the C-band with a mode spacing of at least 0. 3 GHz and a roundtrip unsaturated gain of at least 8 dB over the tuning range. A controller tunes the MEMS filter, which has a filter function whose spectral width is at most ten and preferably less than four times the longitudinal mode spacing, to align its transmission maxima to one of a plurality of discrete output wavelengths that span the C-band. A thermal control element adjusts the longitudinal mode structure to align a single mode with the transmission maxima of the filter. Because the spectral width of the filter function is narrow, laser emission will be limited to a single longitudinal mode.

All-Fiber Q-Switched Laser

View page
US Patent:
7130319, Oct 31, 2006
Filed:
Aug 1, 2003
Appl. No.:
10/633014
Inventors:
Yushi Kaneda - Tucson AZ, US
Christine Spiegelberg - Tucson AZ, US
Jihong Geng - Tucson AZ, US
Yongdan Hu - Tucson AZ, US
Assignee:
NP Photonics, Inc. - Tucson AZ
International Classification:
H01S 3/11
US Classification:
372 10, 372 14, 372 6
Abstract:
An all-fiber Q-switched laser includes a gain fiber spliced between narrowband and broadband fiber gratings that define a polarization-dependent resonant cavity. The narrowband grating is, for example, formed in a PM fiber to create a polarization-dependent reflection band. A modulator applies stress to the fiber chain to induce birefringence and switch the cavity Q-factor to alternately store energy in the gain fiber and then release the energy in a laser pulse.

Distributed Fiber Sensor Based On Spontaneous Brilluoin Scattering

View page
US Patent:
7283216, Oct 16, 2007
Filed:
Jun 22, 2004
Appl. No.:
10/874826
Inventors:
Jihong Geng - Tucson AZ, US
Shibin Jiang - Tucson AZ, US
Christine Spiegelberg - Tucson AZ, US
Assignee:
NP Photonics, Inc. - Tucson AZ
International Classification:
G01B 9/02
US Classification:
356 355, 356477, 356484
Abstract:
A distributed fiber sensor based on spontaneous Brillouin scattering uses a single-frequency fiber laser as a source and a cw Brillouin fiber ring laser as an OLO to optically shift the frequency of the OLO to set the Brillouin/OLO beat frequency within the bandwidth of a conventional heterodyne receiver. The distributed fiber sensor is capable of real-time measurement of both temperature and strain.

Coupled-Cavity Tunable Glass Laser

View page
US Patent:
20030137999, Jul 24, 2003
Filed:
Jan 23, 2002
Appl. No.:
10/055537
Inventors:
Christine Spiegelberg - Tucson AZ, US
Shibin Jiang - Tucson AZ, US
Assignee:
NP Photonics, Inc.
International Classification:
H01S003/30
US Classification:
372/006000
Abstract:
A long-long coupled-cavity glass laser includes a pair of active waveguide cavities that are coherently coupled using a passive waveguide cavity. The active and passive waveguide cavities are of sufficient length so that multiple supermodes and multiple peaks in the coupling coefficient are created over the width of the gain spectra. The supermodes are gain flattened so that the one supermode that coincides with a peak in the coupling coefficient will oscillate. Tunability is achieved by changing the optical path length of either the passive or active waveguide cavities to match a different supermode to a different coupling coefficient peak.

US Patent:
20130208754, Aug 15, 2013
Filed:
Feb 10, 2012
Appl. No.:
13/370729
Inventors:
Leonid Glebov - Orlando FL, US
Apurva Jain - Orlando FL, US
Vadim Smirnov - Orlando FL, US
Christine Spiegelberg - Winter Park FL, US
George Venus - Oviedo FL, US
Assignee:
OptiGrate Corp. - Orlando FL
University of Central Florida Research Foundation Inc. - Orlando FL
International Classification:
H01S 3/08
H01S 3/13
US Classification:
372 99, 35933721
Abstract:
A method for two-dimensional spatial (transverse) mode selection in waveguide and free-space laser resonators and associated laser systems employing said resonators. The invention is based on the cylindrical symmetry of the angular selectivity of reflecting volume Bragg gratings (R-VBGs) that are used as spectrally selective minors in resonators. Matching the divergence of a laser beam and the angular selectivity a reflecting volume Bragg grating can establish different losses for transverse modes of different orders, while not restricting the aperture of the laser resonator, and enables single mode operation for resonators that support a plurality of transverse modes. The invention provides a laser having increased brightness without a decrease of efficiency.
