Abstract

In this paper, we present the new FACTOR-series of fiber coupled high power diode lasers based on single emitters. While fiber coupled modules at DILAS and COHERENT have mostly been based on high power diode laser bars in the past, increased output power, advances in automated alignment processes and reduction in cost of optical components have tipped the scale towards single emitter-based packages in certain areas. The product portfolio includes emission wavelengths between 790 nm and 1060 nm with output power of up to 600 W. Fiber core sizes of 100 µm and 200 µm are offered. All products are available with optional wavelength stabilization to reduce the spectral line width and minimize the wavelength shift over varying output power and temperature. We present Ytterbium pump modules at 976 nm with up to 600 W output power, modules for Thulium pumping at 793 nm with up to 250 W and modules near 880 nm optimized for different absorption peaks of Vanadate, ranging in output power between 65 W and 150 W. In addition to pump modules, industrial turnkey systems for polymer welding and soldering have been developed based on the same product line. Up to 100 W of output power are offered from a 3 HU - ½ 19” rack mountable chassis including the power supply, diode controller, a pilot beam and safety features complying with performance level ‘e’.
