  • Fiber-Coupled, Multibar Module
Feb 2009
DILAS Diodenlaser GmbHRequest Info
MAINZ, Germany, Feb. 10, 2009 – Dilas Diodenlaser GmbH has announced its newest fiber-coupled multibar modules that feature a compact footprint and convenient aiming beam. They deliver 500-W output at 976 nm through a cladding-mode-free QBH high-power 400-μm core diameter fiber with a low numerical aperture of  less than 0.2 and wall-plug efficiency of greater than 35 percent.

DILAS-MultibarModule.jpgPackaged in up to 12-bar configurations, these designs are based on industry standard conductively cooled bars that are optically stacked and polarization-coupled. They require only industrial water for cooling.

The high-brightness, high-efficiency modules have demonstrated a lifetime of greater than 10,000 h in continuous-wave operation.

Custom wavelengths are available upon request. The modules are suitable for direct diode applications as well as for fiber and solid-state laser pumping.

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...
solid-state laser
A laser using a transparent substance (crystalline or glass) as the active medium, doped to provide the energy states necessary for lasing. The pumping mechanism is the radiation from a powerful light source, such as a flash lamp. The ruby and Nd:YAG lasers are solid-state lasers.
