PRODUCT UPDATE LASERS LDMblue
Laserline’s new LDMblue series of blue CW diode lasers offers up to 1kW output power. The lasers operate at 450nm, and are capable of making a controlled heat conduction welding of high reflexive non-ferrous metals, such as copper and gold, in the joining of thin copper bondings in battery technology for electric vehicles. The LDMblue series has also been successfully tested in cladding processes based on non-ferrous metals. Finely-tuned power regulations within milliseconds and the extraordinary calm melt pools offered by these lasers will ensure smooth-seam areas with excellent electrical conductivity, making them interesting for design-oriented applications in visible areas.
The LDMblue diode lasers are available in three E24i
NLight has introduced the element E24i, a 400W fibre-coupled package small enough to fit in the palm of your hand. This power density makes the element e24i an optimal diode for high-power laser systems.
IceFyre 355-30
standard configurations with 1kW, 500W or 300W output power at beam qualities of 100 or 60mm mrad. The compact LDM design for the 19-inch rack enables LDMblue lasers to be integrated easily in a space-saving manner into all common production plants.

The element E24i greatly simplifies system architectures of
direct diode, solid-state, and fibre lasers for industrial, microfabrication, and defence applications. It delivers 400W of output power at 915nm, or 375W at 976nm from a 200µm fibre.

MKS Instruments has introduced the IceFyre 355-30 from Spectra-Physics, a high-power UV picosecond hybrid fibre laser with exceptional cost-performance, stability and reliability. The laser offers high versatility due to its TimeShift ps programmable pulse flexibility, pulse-on-demand and position synchronised output (PSO) triggering. The IceFyre 355-30 combines a power supply and laser head in a rugged, compact package for easy integration into machine tools. It delivers more than 30W average power and up to more than 60µJ pulse energy at 355nm, with adjustable repetition rates from single shot up to 3MHz. Its TimeShift ps programmable pulse capability enables flexible burst mode operation with adjustable burst shape, pulse separation and number of pulses in a burst.
Fully automated, the new laser has excellent power and beam pointing stability, ensuring high precision and reproducibility.

LMWS Pulsed Fiber Laser Welding System
AmadaMiyachiEurope has announced its new compact LMWS Pulsed Fiber Laser Welding System paired with a ML-7370D 70W pulsed fibre laser. The system is ideal for welding dissimilar metals, including copper to aluminium, aluminium to stainless steel and steel, and copper to stainless steel. An example application includes the joining of aluminium and copper battery tab material. It is also a good choice for copper-stainless steel thin sheet welding and plastic welding. Tests have shown that the new high-speed fibre laser welding system works well for welding thin metals up to 250μm thick. This is an ideal tab thickness for battery cans with wall thicknesses of 300-350μm. The new technology features shorter
,
pulses with a higher peak power than traditional laser options. The shorter pulse results in less mixing of materials, and hence less of an intermetallic zone and less brittleness with copper and aluminium tab materials.
The LMWS unit can be used for several weld types, including single point object arrays, basic shapes (rectangle, circle, spiral), wobble function and vector graphics including CAD and line-drawings, and logos. In addition, by simply changing its settings, the unit can also be used to mark, engrave, cut, drill, and ablate thin materials.
This versatile high-power, high-speed laser is available with a variety of integration options to match process needs. It comes standard with an XY galvanometric scanner. A rotary stage option is also available.
