Laser Efficiency Increased Using Ceramic in Optical Pumping Cavities

Lasers have been used in medicine for many years, mostly as minimally invasive surgical cutting tools. However, in recent years there have been many advances in the market, and the range of applications for lasers and light-based systems continues to expand across several specialities, especially in ophthalmology and cosmetic treatments. This has created a demand for increased efficiency of lasers and high intensity pulsed lamps, while creating new systems that are more compact, gentler, quicker and more cost-effective.

Integrated Solar Modules Provides Mobility

The mobile world reaches its limits every time the power supply runs out. There must surely be huge market potential for devices that take their energy from the daylight just as effortlessly as we breathe oxygen from the air. Integrated solar modules can provide the solution. Integrated solar cells are already being used to power wrist watches and pocket calculators. But a significantly higher output is needed in order to feed power-hungry devices, such as cellphones or palmtops.
