Feature laser technology articles by leading photonics researchers & engineers from industry, academia, or government laboratories. Topics include in-depth coverage of lasers and sources, fiber optics, optics, imaging, detectors, instrumentation and photonics
- A group of Ukrainian students, with assistance of the OSA, created a course, "A Practical Course for Young Scientists," to help young scientists plan their careers.
- Embedded thermoelectric coolers (eTECs) are smaller and thinner than conventional TECs and show promise for direct integration using standard high-volume manufacturing methods.
- OSA Foundation grants to OSA student chapters and local sections benefit students throughout the world.
- An ancillary benefit of improved telecom sources has been in other areas requiring tunability such as measurement and fiber-optic sensing systems.
- Improved power scaling of fiber lasers is being enabled by advances in high-brightness pump laser diodes—specifically, higher efficiency of the pump semiconductor material itself allowing more power per emitter, and innovations in coupling the diode energy into the target delivery fiber.
- Combining laser beams can boost power at the target far above that produced by a single laser. Incoherent beam combining achieves propagation efficiencies of greater than 90%, while avoiding the complexities of coherent or spectral beam combining.
- The OSA's Traveling Lecturer Program gives members worldwide an opportunity to hear industry luminaries give presentations in a small setting.
- The Presidential Award for Excellence in Mathematics and Science Teaching is the highest recognition that a mathematics or science teacher can receive for outstanding teaching in the United States.
- Optoelectronics technology is equipping cars with "active" safety features that work as hard as drivers to prevent accidents.
- Laser-diode controllers provide constant current to laser diodes, as well as solutions to system-design tasks.
