The company first developed its green TruDisk disk laser line as a solution to the challenge of laser welding copper.
Based on the obtained results, the appropriate welding parameters were designed to realize the real experiments of the laser welding of dissimilar Ti-Al alloy sheets by the TruDisk 4002 disk laser. The quality of the prepared weld joints was evaluated by light microscopy, EDX analysis, X-ray diffraction analysis, tensile testing, and microhardness measurements.
Design of solder / substrate joint was carried out on solid-state disk laser with a maximum power of 2 kW from the Trumpf company.

She added that if the initial colour of the pump light is tunable, for example that provided by a semiconductor disk laser, we can achieve tuning of the Raman laser colour.
The disk laser is a brilliant combination of a solid-state laser and a semiconductor laser.
According to TRUMPF's Frank Geyer, product manager, Laser Systems, this disk laser can productively handle many 3D cutting applications.
Today, a 4-kW disk laser is about $250,000, and prices keep coming down." He adds that the introduction of Trumpf's next-generation disk laser later in 2012 will further the cost savings for customers.
