Laser Focus World magazine for November 2011 edition has been released. You can read latest news and developments in advanced semiconductors, medical equipment, lasers, optics and aviation and aerospace in this issue. Here are feature articles for this month.
THIN-FILM COATINGS: Military laser technologies challenge optical-coating manufacturers
Optical coatings for military applications often need to simultaneously satisfy many extreme requirements; coating manufacturers have responded with an array of design and fabrication approaches.
PHOTONIC FRONTIERS: HIGH-POWER LASER DIODES: Bringing high brightness to high-power laser diodes
High-power laser diodes excel in generating light efficiently, but they have fallen short in producing the high-quality beams needed for many applications. New laser designs, and new twists on beam combination, are making high-power diode beams brighter.
SINGLE-PHOTON DETECTORS: Planar architecture optimizes Si single-photon-counting detectors
A new planar structure for silicon single-photon-counting detectors leads to the doubling of detector efficiency while maintaining picosecond timing resolution, low dark counts, and low power consumption.
PHOTONICS APPLIED: AESTHETIC PHOTONICS: Looking good with lasers
Aesthetic photonics for wrinkle and hair removal, eye and cosmetic surgery, and laser liposuction, just to name a few, are part of a growing aesthetic medical device business forecasted to reach nearly $3 billion by 2016.
TERAHERTZ IMAGING: Terahertz reflectometry images faults in silicon chips
Terahertz imaging microprobes boost the accuracy of reflectometry-based fault location in silicon chips into the sub-micron range.
TUNABLE SOURCES: Quantum cascade lasers enter industrial applications
Known as a mid-IR tool for research or military applications, tunable quantum cascade laser-based systems are now available for spectroscopy applications that include detecting anesthetic gases used in surgery and identifying hazardous materials found in chemical spills or industrial workplaces.
FIBERS FOR SENSING: Fiber-optic Fabry-Perot sensors take the strain under high temperature
Directly engraved on silicon or sapphire fibers using a 157 nm laser micromachining system, highly accurate micro fiber-optic Fabry-Perot interferometric (MFFPI) sensors are well suited to harsh environments.
