Intense to Develop Laser Diode Arrays for the
European Space Agency

Photonics Spectra
Oct 2007
A developer of semiconductor lasers, Intense Ltd. of Glasgow, UK, has signed a contract with the Paris-based European Space Agency to develop high-power, efficient laser diode arrays for solid-state laser pumping applications in space. The focus of the program, called PULSAR (pump laser stacks with aerospace reliability), is to enhance the effectiveness of the stacks at the 808-nm wavelength. The arrays will target a power of 1.2 kW under pulsed operation with an electro-optical conversion efficiency of 65 percent. The increased efficiency will enable power savings aboard space vehicles and will reduce heat-removal requirements.



GLOSSARY
photonics
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
