THz QCL Hits Light Output Milestone
Using special symmetrical laser structures, a group in Vienna says it has created a terahertz quantum cascade laser (QCL) with four times higher light output than other such existing devices, crossing a major hurdle to the widespread use of such lasers. "We achieved 470-mW peak output power in pulsed mode from a single facet at a heat sink temperature of 5 K and a maximum operation temperature of 122 K. Furthermore, the devices show a broadband emission spectrum over a range of 420 GHz, centered around 3.9 THz," the group said in a paper on the work.

Rare-Earth Doped Fibers for Use in Fiber Lasers and Amplifiers
Monday, November 4, 2013 1:00 p.m. EST
FREE WEBINAR
The advances in performance of fiber lasers have been dramatic in the past 10 years, making fiber lasers a commercial business worth more than $500 Million per year. All of this is made possible by the unique performance attributes of rare-earth doped silica fibers, which are at the heart of each of these laser systems. In this webinar, we will describe the key parameters of these fibers, including the use of large-mode-area (LMA) fibers for high-power CW lasers as well as pulsed fiber lasers, along with the key other fiber-based components needed to make a fiber laser. The common rare-earth dopants for silica fibers, namely Ytterbium, Erbium, Thulium and Holmium, will also be described, along with some of the commercially relevant devices that are enabled by these fibers.

Replacing Mammography with Light and Ultrasound
A new device called a photoacoustic mammoscope combines infrared light and ultrasound to create 3-D maps of the breast. Its creators in The Netherlands hope that it could someday replace the x-rays used in traditional mammography for routine breast cancer screenings.
