Nd:YAG laser News
NIH Grant Supports Light, Ultrasound Combination in Breast Imaging
BUFFALO, N.Y., Sept. 30, 2020 — National Institutes of Health (NIH) funding to SUNY Buffalo is supporting the college’s development of a portable breast imaging device called a dual scan mammoscope (DSM). By pairing light with ultrasound technology, the imaging system...
Industrial Laser Proves Effective at Removing Nonstick Coatings
CÓRDOBA, Spain, March 22, 2019 — The Manufacturing Processes Engineering research group at the University of Cordoba has validated a new method for the removal of anti-adherent fluoropolymer coatings using a continuous-wave (CW) Nd:YAG laser. The research focused on the factors...
Laser Process Shows Promise for Skin Cancer Treatment
CAMBRIDGE, Mass., Feb. 7, 2014 — The treatment of basal-cell carcinoma (BCC) with a new combination of lasers – pulsed dye and Nd:YAG – has yielded some good results, offering the potential for nonsurgical treatment.
Atmospheric laser propagation
WASHINGTON – An underwater photo-ionization laser acoustic source developed by researchers at the US Naval Research Laboratory could enable remote acoustic generation from compact air- and shipborne lasers, allowing aircraft to communicate without the need for...
PW10: Variety at Edmund Optics
SAN FRANCISCO, Jan. 29, 2010 – Flexibility was a recurring theme among exhibitors at SPIE Photonics West this year, and Edmund Optics (EO) was no exception: The Barrington, N.J.-based company had a large number of new and recent products on display, including hands-on...
Laser Speeds Up Microfluidics by 20 Times
Jul 1, 2007 — Microfluidic systems can enable multiple rapid reactions between chemicals in fluid form. But because forces resistant to fluid flow dominate on a microscopic scale, chemicals may mix together slowly and incompletely. To increase the speed of fluid...
Imaging Reveals Details of Bats in Flight
Jun 1, 2007 — Birds and bats approach flying differently. When flying at slow speeds, birds easily can separate the primary feathers on their wings to allow air through, which makes their upstroke aerodynamically inactive. The membranes on a bat wing, however,...
Cooling — with a Light Touch
Dec 1, 2006 — To make a mirror really cold — and possibly help reveal quantum effects in the macroscopic world — scientists are turning to the chilling effects of a photon breeze. In the Nov. 2 issue of Nature, three groups of researchers demonstrated that...
Titanium Nanoparticles Produced by Laser Ablation in Liquid Are Studied
Oct 1, 2006 — As applications of nanoscale materials continue to be developed, a fundamental understanding of how changes in the processes that create those materials affect their resulting properties is required. To that end, A. Welford Castleman Jr. and Justin...
Study Shows Laser Shipments Sound
Nov 1, 2005 — Following the release of a report by the Laser Systems Product Group of the Association for Manufacturing Technology in McLean, Va., Dave Plourde, chairman of the association and vice president of sales at Preco Laser Systems LLC of Somerset, Wis.,...
Daily News Briefs
Jul 27, 2004 — Lumenis Ltd., a maker of laser and light-based devices used for medical and aesthetic applications, announced that its Quantum SR intense pulsed light (IPL) system will be used in a multicenter Phase II clinical study to be carried out in the US by...
Frequency-Doubled Nd:YAG Generates 200 W
Jul 1, 2004 — A high-power green Nd:YAG laser has been developed at Mitsubishi Electric Corp.'s Advanced Technology R&D Center in Amagasaki, Japan, and is being studied for the crystallization of amorphous silicon films into polycrystalline silicon films...
Raman Spectrometer Probes the Deep
Mar 1, 2004 — As NASA rovers equipped with high-tech instruments again investigate the surface of Mars, it can be difficult to appreciate that places much closer to home have resisted such in situ analyses of rocks and minerals. But the deep-sea floor remains as...
Restored 'David' Had Laser Treatment
Jan 22, 2004 — CHELMSFORD, Mass., Jan. 22 -- When Italy's National Museum of the Bargello, in Florence, decided to put Verrocchio's David on the road in the US, conservators wanted the 15th-century, four-foot bronze sculpture to look its best. Its recent...
Restored 'David' Received Laser Treatment

Crystal Offers High Fourth-Harmonic Conversion Efficiency
Oct 1, 2003 — Few nonlinear crystals are available whose transmission and nonlinearities are compatible with the efficient generation of the fourth harmonic of Nd:YAG at 266 nm. KBe2BO3F2 (KBBF) has many desirable parameters: It has a high damage threshold and...
Compensating Thermal Effects in Rod Lasers
Jul 1, 2003 — By forcing an Nd:YAG laser to operate in radial or azimuthal polarization, a team at Soreq Nuclear Research Center in Yavne, Israel, has overcome the thermally induced beam-quality aberrations commonly associated with solid-state rod lasers. The...
Trapping Center Controls Spin Direction
Feb 1, 2003 — In continuing work on the development of optically driven micromotors, physicists at Kyoto University in Japan have demonstrated that the location of the trapping center determines the direction of rotation of a chiral object. They reported their...
