CREOL Wins Research Funding
Apr 1, 2006 — The Center for Research and Education in Optics and Lasers (CREOL) at the University of Central Florida in Orlando is the recipient of US Department of Defense Multidisciplinary University Research Initiative awards. The center will lead the research on two awards and participate in two other initiatives. Investigators from the center and other institutions will study negative-index materials, high-power fiber lasers, ultrafast switching for optical imaging, and ultrafast laser interaction...
Mode-Locked Fiber Laser Oscillator Generates Multiwatt Output
Apr 1, 2006 — Laser users requiring multiwatt outputs from mode-locked lasers have been forced to resort to bulk lasers (i.e., those based on rods or slabs) or on complex and expensive master oscillator power amplifier fiber configurations. Recently, however,...
Fiber Laser Has Helical Core for High Single-Mode Power
Mar 1, 2006 — As laser designers seek ever-higher powers from single-mode fiber lasers, they encounter a fundamental roadblock. A small core in a fiber laser forces single-mode oscillation, but the spatial intensity in a small-core, high-power laser is great...
IPG Photonics Turned Fiber Bust Into Laser Boom
Jan 6, 2006 — OXFORD, Mass., Jan. 6, 2006 -- IPG Photonics Corp.'s world headquarters is striking yet understated. Set back from a sparsely populated but well-trafficked industrial route in Oxford, Mass., on 62 acres -- about 12 miles from Worcester in an area...
Fiber Laser Generates Multiple Wavelengths
Jan 1, 2006 — Multiwavelength fiber lasers are important for testing wavelength division multiplexing telecommunications systems and for other applications in metrology and sensing. Unfortunately, there is a fundamental obstacle standing in the way of...
Simple Technique Tunes a Fiber Lasers Wavelength
Jan 1, 2006 — The broad spectral linewidths of fiber lasers make them attractive candidates for versatile, wavelength-tunable sources, but the wavelength-tuning mechanisms — often involving multimode fiber Bragg gratings or other complex components — are neither...
Fiber Laser Generates 1.6 W in Single Longitudinal Mode
Dec 1, 2005 — Researchers at the University of Arizona’s College of Optical Sciences in Tucson have generated 1.6 W at 1550 nm in a single longitudinal mode from a short, cladding-pumped Er:Yb codoped fiber laser. They believe that theirs is among the...
Single-Mode Fiber Laser Generates 125 W Tunable over 20 nm
Dec 1, 2005 — Powerful single-frequency lasers are required for many scientific and engineering undertakings, such as gravity-wave detection and coherent combination of multiple beams. Such sources also have potential as very high power transmitters in...
News Briefs
Nov 16, 2005 — Bruker AXS Inc., a Madison, Wisc., maker of analytical x-ray systems for elemental analysis, materials research and structural investigations, said Tuesday it has closed its acquisitions of Roentec AG and the microanalysis business of Princeton...
Erbium Fiber Laser Generate Supercontinuum
Nov 1, 2005 — Researchers at the University of Tokyo have demonstrated a compact, self-contained supercontinuum laser based on the addition of a length of highly nonlinear dispersion-shifted fiber inside the resonator of an erbium-doped fiber ring laser. The...
IPG Photonics Sells System to US Navy
Nov 1, 2005 — IPG Photonics Corp. of Oxford, Mass., will supply a 10-kW continuous-wave ytterbium fiber laser system under a commercial procurement contract awarded by the US Naval Surface Warfare Center in Crane, Ind. The water-cooled YLR-10000, with a central...
Alfalight Develops Laser Diodes for SHEDS
Oct 1, 2005 — Alfalight Inc. of Madison, Wis., was awarded $1.4 million in funding for Phase II of the Super High Efficiency Diode Sources (SHEDS) program, sponsored by the Defense Advanced Research Projects Agency. The allotment follows the company’s completion...
Four-Wave Mixing Trumps Homogeneous Gain in Erbium Laser
Oct 1, 2005 — Although current wavelength-division multiplexing (WDM) systems require a different laser for each wavelength transmitted over an optical fiber, engineers envision more-efficient systems in which a single laser will emit all of the necessary...
Linear Optical Amplifier Generates Multiple Wavelengths Simultaneously
Oct 1, 2005 — The previous report describes a technique to finesse mode competition in a homogeneously broadened erbium-fiber laser. Researchers at Hong Kong Polytechnic University in Kowloon, China, have taken the opposite approach to obtaining multiple...
DIODE LASER SITE
Sep 1, 2005 — A redesigned Web site has been launched by unique-m.o.d.e AG, an OEM diode laser and system supplier for several markets, including micromaterials processing, medicine and laser pumping. Based on a customer relationship management system, the...
Eye-Safe, Wavelength-Tunable Fiber Laser Generates >100 W
Sep 1, 2005 — Eye-safe lasers -- those that emit in the 1.5-µm region where the cornea does not transmit -- are important for many applications, including free-space communications, remote sensing and rangefinding. Significant power levels often are required...
Princeton Lightwave Gets More Funding for Solid-State Lasers
Aug 25, 2005 — CRANBURY, N.J., Aug. 25 -- Princeton Lightwave Inc. (PLI), a producer of near infrared, high-power diode lasers and application specific detectors for optical communications, defense and sensing applications, announced that the US Department of...
