Researchers at the University of Bath, United Kingdom have created a new kind of laser capable of pulsed and continuous mid-IR emission between 3.1 and 3.2 microns, a spectral range that has long presented a major challenge for laser developers. The achievement could aid in the development of new uses for mid-IR lasers, which are currently used in applications such as spectroscopy, environmental sensing and detecting explosives.

Cree boosts performance of LEDs
By leveraging key elements of its SC5 Technology Platform, the Cree XP-L and XP-G2 LEDs now provide up to nine percent more lumens and lumens-per-watt (lpw) than previously available. These enhancements allow lighting manufacturers to quickly increase performance for existing designs without any additional investment or requalification. Sharing the same 3.45 x 3.45-mm footprint, the XLamp XP-L LED delivers up to 1,150 lm, while the XLamp XP-G2 LED delivers up to 586 lm, both at 85°C. These LEDs have 10,000 hours of LM-80 data available at 105°C, delivering reported L90 lifetimes of greater than 36,000 hrs, which is less than 10 percent light loss after four years.

Cree also set another lumens-per-Watt record for a single high-power LED that delivers nearly 1,600 lm at 134 lpw, a 25% increase over production LEDs of similar color quality. To put this into context, a current 60-W LED replacement lamp with average light quality (3000K and 80 CRI) could now be upgraded to incandescent-like light quality (27 00K and 90+ CRI) with the same light output and power consumption levels at no additional cost.
