TRUMPF develops technology for high-brilliance direct diode lasers

The laser and laser system manufacturer TRUMPF recently unveiled its TruDiode 4001.5 technology demonstrator at LASER World of PHOTONICS in Munich. Based on a new, patented technology known as Dense Wavelength Multiplexing (DWM), the 4 kW direct diode laser offers a brilliant beam quality of 5 mm•mrad, enabling it to be connected to a laser light cable with a core diameter of 150 µm. By way of comparison, commercially available direct diode lasers in the high-power segment typically have beam qualities of between 30 and 50 mm•mrad and are used with a 600 µm laser light cable.
