Fiber-coupled laser module for fiber- and solid-state laser pumping introduced by Dilas

MAINZ, Germany, 4 Oct. 2009. Diode laser specialist Dilas in Mainz, Germany, is introducing a multi-bar fiber-coupled laser module that delivers as much as 80 Watts output from a 400-micron fiber at 808, 976, and 1550 nanometers for direct diode applications as well as fiber and solid state laser pumping.

The fiber-coupled, multi-bar laser module delivers 808- and 976-nanometer wavelengths at 80 Watts output power, and 1550 nanometers at 30 Watts, through a 400-micron core diameter fiber with a numerical aperture of less than 0.22 and WPE of more than 35 percent.

The two-bar design is based on industry standard conductively cooled bars, which can be cooled with industrial grade water or thermo electrical air-cooling. This module has demonstrated a lifetime greater than 10,000 hours at 80 Watts continuous wave operating condition.

Custom wavelengths are available. These modules include an integrated pilot beam, power sensor, fiber interlock, and user-exchangeable protection window. For more information contact Dilas online at www.dilas.com.
