Abstract
High-brightness fiber coupled laser modules are presented with output powers of more than 75W and electro optical efficiencies of more than 45%. An ongoing lifetime test shows nearly 3000h reliable operation. A wavelength stabilization using external gratings is shown with stable wavelength locking over a large temperature range. To combine the output powers of the fiber coupled modules fiber combiners were used and powers in the 400 and 1000W range were achieved for output fibers of 200 and 400μm, respectively.
