Thin-film plate polarizers from Alpine Research Optics are optimized for use with Nd:YAG, Nd:YVO4, and Nd:YLF lasers operating at 1064, 1053, 532, 355, and 266 nm.
The announcements earlier this year by Sumitomo (Kyushu, Japan) and Osram Opto Semiconductors (Regensburg, Germany) that they each have developed green-emitting laser diodes (...
The Emil Wolf Outstanding Student Paper Competition was established by the OSA Foundation to recognize the contributions of Dr.Wolf, a professor of optics at the University of...
A spectral-broadening technique developed by Tamas Nagy and Peter Simon at the Laser-Laboratorium Göttingen has allowed them to produce sub-25-fs deep-UV pulses with an energy...
A green-emitting optically pumped semiconductor laser (OPSL) introduced on June 12 by Coherent (Santa Clara, CA) is potentially a big deal in the scientific-laser marketplace,...
In his Photonic Devices and Applications Plenary presentation, “Photonic Metamaterials: Optics Starts Walking on Two Feet,” at the 2009 SPIE Optics and Photonics Conference (Aug...
Collection of three-dimensional (3-D) data from confocal scanning microscopy and optical coherence tomography (OCT) is lengthy due to the sequential acquisition of image pixels...
Researchers in Germany have demonstrated the long-postulated “phonon laser”—a system for the resonant oscillation and coherent amplification of vibrational energy packets in perfect...
Flexible displays are not known for their durability. Often based on organic LED (OLED) technology, they suffer from a fundamental problem: if the display is to bend, the light...
The properties of optical fibers can be tailored to match specific operating conditions and enable fiber-optic systems to operate in a broad range of hostile settings.
With blue laser diodes in wide use in BlueRay DVDs, bridging the green gap from the blue end is a lingering challenge that is being met through improved epitaxial semiconductor...
Tailoring the internal structure of metamaterials to vary optical properties controls how they transform light—leading to applications from optical cloaking to the optical counterparts...
Just after researchers at Norfolk State University (Norfolk, VA), Purdue University (Purdue, IN), and Cornell University (Ithaca, NY) announced a tiny laser fabricated from a ...
