TRUMPF brings new ultrashort pulse lasers to Photonics West 2023

FARMINGTON, Conn., January 31, 2023 – The high-tech company TRUMPF will bring two TruMicro ultrashort pulse lasers, a TruMicro 6020 and TruMicro 2030, to the Photonics West 2023 trade show in San Francisco, California. The TruMicro 6000 and TruMicro 2000 product families feature new technology platforms to boost power and enhance versatility. Ultrashort pulsed lasers are often used in electronics manufacturing to produce printed circuit boards, displays and similar products. With 100 watts, the TruMicro 2000 series is a powerful industrial ultrashort pulse fiber laser. The TruMicro 6000 series offers up to 200 watts at pulses in the femtosecond range for even higher performance. The TruMicro 2030 and TruMicro 6020 can be converted to green (515 nm) and UV (343 nm) wavelengths while maintaining high beam quality.

TruMicro 6000 featuring new slab technology

The next-generation TruMicro 6000 lasers are ideally suited for high energy input and have a burst-mode for even higher accumulation of energy. The ultrashort pulse lasers are useful for a variety of industries and applications which include laser cutting and modification of transparent materials. The laser is slab amplified; the active medium, a crystal that amplifies laser light, looks like a tile or slab. The laser light travels through the slab, zigzagging between its two end faces. The slab’s advantage is that this active medium is very conducive to cooling, which enables high pulse energies at high repetition rates. A closed-loop feedback control ensures the stability of the power and pulse energy.

With pulse energies of several millijoules, the TruMicro 6000 lasers are excellent tools for drilling and modifying glass up to six millimeters thick. The TruMicro 6020 offers single pulse picking, “Pulse on Demand,” and a pulse duration of 850 femtosconds. Ultrashort pulses reduce thermal stress on highly sensitive materials. High peak pulse power levels enable excellent quality paired with maximum productivity.

TruMicro 2000 – an extremely versatile tool

With an average power output of up to 100 watts, the TruMicro 2000 series lasers accelerate the machining process. The fiber-based TruMicro 2000’s parameters such as pulse duration, repetition rate and pulse energy can be variably adjusted within milliseconds to suit a wide range of use cases. The duration and energy of individual pulses remain remarkably stable. The pulses can serve many purposes, for example to machine surfaces and to mark a wide variety of materials ranging from glass and plastics to corrosion-resistant metals or to cut highly sensitive medical products such as stents.

The compact, lightweight design of the TruMicro 2000 laser makes it easy to integrate into production. Another notable feature is that the new lasers may be used with an LLK-U fiber optic cable. This type of cable makes it easier to apply ultrashort pulses in industrial use cases. The hollow-core fiber enables laser light to take a stable, simple path from the beam source to the optics and straight to the part without having to be redirected by a complex free-beam guide or several deflection mirrors. No free-beam guidance is necessary.
