Trumpf unveiled two new highly productive TruMicro ultra-short pulsed lasers for micromachining. With double the output of the predecessor models, the two new additions are currently the most powerful industrial picosecond lasers on the market and are due to take their place on highly automated production lines. The new infrared laser TruMicro 5070 has an impressive output of 100 watts at a wavelength of 1030 nanometers. The TruMicro 5270 generates 60 watts of power and reinforces the portfolio of green lasers with a wavelength of 515 nanometers. These lasers offer an outstanding combination of extremely short pulses of less than 10 picoseconds and high pulse energies of up to 250 microjoules. The high productivity of the lasers is supplemented by excellent beam quality (M² < 1.3) and high process reliability, irrespective of the set output. The beam characteristics, such as quality and position, and the pulse-to-pulse stability remain absolutely stable thanks to two-stage laser-power regulation. The TruMicro 5070 and the TruMicro 5270 extend the TruMicro series "upwards"; the tried-and-tested TruMicro 5050 in the infrared range and the green TruMicro 5250 models will remain in the portfolio.

The new picosecond lasers in the TruMicro series 5000 vaporize virtually any material so fast that there is no detectable influence of heat. As a result, materials can be machined "cold" with no mechanical or thermal stress - which makes these lasers ideal for machining semiconductor materials, metals, dielectrics and plastics. As part of a live demonstration at Productronica, the TruMicro 5270 will be cutting 0.3-millimeter-thick display glass for use in smartphones, tablet PCs and LCD screens. The new members of the TruMicro family are perfectly suited to electronics production, for instance in cutting ceramics, structuring metal surfaces and burr-free drilling of silicon and other materials. Other applications include rapid ablation of dielectric or metallic layers and cutting carbides and polycrystalline diamond for grinding and cutting tools.

The low total cost of ownership of the TruMicro lasers over the entire lifecycle is unrivalled, while the high precision and reproducible quality of machining does away with the need for time-consuming and costly finishing work. The high output coupled with reliable process stability ensures excellent throughput rates, which keeps down the total costs in relation to the cost per part.
