A wealth of laser expertise focused in one place

“Power of Choice” is the slogan that best describes the numerous new solid-state laser and CO2 laser beam sources for material processing TRUMPF will be presenting at the LASER World of Photonics 2013. The first prototype of an ultra-short-pulse laser for scientific applications from TRUMPF Scientific Lasers will also be on show at the trade fair.

Short-pulse and ultra-short pulse lasers for micro-processing
Micro-expertise is a particular focus of TRUMPF’s exhibits at this year’s trade fair. TRUMPF is adding four new beam sources to its portfolio of short-pulse and ultra-short-pulse lasers for the micro-processing of materials. The infrared-wavelength TruMicro 5080 expands the power capability of picosecond lasers to over 150 watts average output, breaking another record for industrial-use ultra-short-pulse lasers. The frequency-doubled, green-wavelength variant, the new TruMicro 5280, also surpasses the 100-watt mark for average output. However, TRUMPF is also strengthening its portfolio at the lower-power end of the spectrum. The new picosecond lasers from the TruMicro Series 2000 are entry-level models for micro-processing materials in the low-average-output range. Together with their high beam quality, this makes them suitable for applications such as cutting polyimide and structuring glass. TRUMPF also offers this series in green and infrared wavelengths.

Ultra-short-pulse lasers for scientific research
At the trade fair, TRUMPF Scientific Lasers is unveiling for the first time the prototype of a laser pump source for scientific applications in the femtosecond range. The lasers in this SDL series deliver pulses of one picosecond and pulse energies of up to 50 millijoules. This makes them an ideal basis for optical parametric amplification stages (OPA), which are used to generate high-energy femtosecond pulses. These OPAs will shortly join the TRUMPF portfolio as lasers that are well suited to scientific applications, such as spectroscopic examinations.

New marking laser capabilities
TRUMPF is presenting a world first in Munich with its new TruMark Series 1000. The new infrared-wavelength marking laser has an extremely compact design: the beam source, power supply unit, computer, and even the scanner all fit inside a box which is the size of a shoe box and weighs only around ten kilograms. This makes it easy to integrate the laser into both existing and new production lines. Although the marking laser represents an affordable entry point into the world of laser marking, it also bears comparison with the TruMark Series 3000 and 5000 in terms of quality and functionality, as readily testified by the automatic focal position control of TruMark 1000. But TRUMPF is also expanding its marking laser portfolio at the higher end of the output scale. The new fiber laser from the TruMark Series 5000 is suitable for the rapid processing of high quantities of both metal and plastic parts.

Compact direct diode lasers
Another highlight is the new direct diode laser generation with output powers of up to six kilowatts for brazing and cladding. The new TruDiode 6006 impresses with its energy efficiency of 40 percent and extremely low operating costs in general. This is all down to a simple, space-saving laser concept, making TruDiode 6006 the most compact diode laser in its power class available on the market. Moreover, it offers excellent value for money thanks to its simple and smart laser design.

New generation of disk lasers
Also on exhibit at the trade fair is the new generation of TruDisk disk lasers, which deliver laser output powers of up to six kilowatts from a single disk. This facilitates an even more compact design and leads to a significant reduction in operating costs of up to 25 percent. Special attention was devoted to bringing down energy consumption. The efficiency of the new generation is as high as 30 percent. A redesigned control system with intelligent energy management ensures that the laser is always in an optimum energy state, even during breaks in operation. The new generation also scores highly for being robust even under extreme environmental conditions. The youngest member of this series is the new TruDisk 2000, which is being exhibited for the first time in Munich. Its outstanding beam quality makes it ideally suited to cutting and welding operations.

Diffusion-cooled CO2 lasers
Introducing the new TruCoax 1000 generation, TRUMPF presents a compact and robust CO2 laser for processing metallic and non-metallic materials. TruCoax 1000 achieves very good beam quality of over 1.1 M2 and a peak pulse output of up to several kilowatts, enabling extremely fast and precise processing. Furthermore, the geometrical and optical specifications of TruCoax 1000 ensure outstanding beam and output stability and hence reproducible application results even at high speeds and during the whole service life. The coaxial laser works with a transistor-driven high frequency generator, which fits under the hood of the laser. This makes TruCoax 1000 an energy-efficient and compact laser that customers can easily integrate into their own individual systems. Uniquely for lasers in its class, TruCoax 1000 is completely maintenance-free, so there is no need to replace premix gas or HF tubes or even for a refurbishment. Operating costs are therefore minimal. These qualities make TruCoax an extremely reliable and cost-effective laser for industrial manufacturing.
