BALTIMORE and SEATTLE, March 12, 2014 — A new imaging catheter that enables real-time, ultrahigh-resolution OCT imaging at 800 nm to form a 3-D volumetric dataset could potentially improve image contrast via increased light scattering and less tissue absorption.

ARLINGTON, Texas, & CAMBRIDGE, Mass., Oct. 4, 2013 — A new type of near-infrared microscopy can image cells through a silicon wafer, providing more information about diseased or infected cells flowing through microfluidic devices. “This has the potential to merge research in cellular...

VIENNA – Optical coherence tomography light sources will shrink to one-fifth the size of conventional devices with the help of a tapered laser being developed by the European Union project FAMOS (Functional Anatomical Molecular Optical Screening). ...

VIENNA – OCT light sources will shrink to one-fifth the size of conventional devices with the help of a tapered laser being developed by the European Union project FAMOS (Functional Anatomical Molecular Optical Screening). Seventeen partners have joined...

VIENNA, March 26, 2013 — Optical coherence tomography (OCT) light sources will shrink to one-fifth the size of conventional devices with the help of a tapered laser being developed by the European Union project FAMOS (Functional Anatomical Molecular Optical Screening).

CAMBRIDGE, Mass. – A new ultrafast time-of-flight imaging technique uses reflections from a nonmirrored surface to recover 3-D shapes hidden from sight, essentially allowing the camera to capture images around corners. Scientists at MIT’s Media Lab...

CAMBRIDGE, Mass., March 21, 2012 — Using reflections from a non-mirrored surface, a new ultrafast time-of-flight imaging technique recovers 3-D shapes hidden from sight, essentially allowing the camera to capture images around corners.

NORWICH, England, March 6, 2012 — A £466,000 grant from the Engineering and Physical Sciences Research Council will help University of East Anglia scientists develop ultrafast laser equipment capable of generating femtosecond-scale intense light pulses from the ultraviolet to the...

Jul 1, 2010 — This issue of Photonics Spectra may be the final installment of our three-month special feature article celebration of the laser’s 50th anniversary, but the party isn’t over. This month’s laser features include an article by...

Feb 1, 2008 — The venerable Ti:sapphire laser has always been the workhorse of ultrafast technology, but it is an expensive beast, partly because it requires expensive green pump lasers. Cr3+-doped colquiriites (Cr:LiSAF, Cr:LiSGaF and Cr:LiCAF) also can be...

Jan 1, 2008 — Fabricating nanoscale polymer thin-film structures mightbecome easier, thanks to researchers from Kansas State University in Manhattan. Such structures could be used in chemical and biological sensor arrays, as optical elements, for electronic...

Jul 1, 2005 — The quantum defect -- the energy difference between a pump photon and a laser photon -- is one of the most significant parameters in selecting a potential laser material. Another one for a solid-state laser is the material's thermal ruggedness, or...

Jan 1, 2005 — Thales Laser, which has offices in Europe, Asia and the US, has received a $1.8 million contract to install a 100-TW Ti:sapphire laser in the physics department of the University of Nebraska-Lincoln. The device, which will operate at 10 Hz, is based...

Sep 1, 2004 — Unlike common ferromagnets used in everything from compasses to spintronics, antiferromagnets still have fairly limited application potential, in part because of the lack of understanding of the magnetization process for such materials. Now...

Jan 1, 2004 — Using an effect related to electromagnetically induced transparency, scientists at Harvard University in Cambridge, Mass., have stopped pulses of light in an atomic medium and released them a few microseconds later. The development opens prospects...

Jan 1, 2004 — At a time when job prospects are nonexistent for many recent college graduates, technical majors are still finding employment, according to David Brady, professor and director of the Fitzpatrick Center at Duke University in Durham, N.C. University...

Aug 1, 2003 — A group at the Communications Research Centre Canada in Ottawa has presented an alternative means of writing fiber Bragg gratings that uses femtosecond pulses of 800-nm radiation from a Ti:sapphire laser. The advantage of such an approach, according...

Feb 1, 2003 — A team at Universität Hannover in Germany has produced interferometer structures for atoms by focusing the near-IR output of a Ti:sapphire laser through arrays of microlenses to generate patterns of optical dipole potentials. The work, which...

Jan 1, 2003 — A hands-free, single-box, ultrafast Ti:sapphire laser from Coherent Inc. in Santa Clara, Calif., the Chameleon provides femtosecond-pulse tuning from 720 to greater than 930 nm. Developed primarily for multiphoton excitation microscopy, this...
