Ditzingen, 27, January 2014 – The new TruMicro 5070 Femto Edition offers pulse duration of 800 ± 200 femtoseconds and pulse energy as high as 200 microjoules. The repetition rates are at 400 and 600 kilohertz. The new femtosecond laser does its work with a remarkable 80 watts of mean power. Just like the TruMicro 5050 Femto Edition, the new ultrashort pulse laser is based on the TruMicro 5000 Series and thus offers unconditional suitability for industrial use, without downtimes or variations in the results of processing, even when running in a three-shift operation. The reason for this is the extraordinary stability of the pulses and power of this TRUMPF model. These are achieved by separating pulse generation and pulse emission. Patented controls monitor each individual pulse and keep the power and pulse energy at exactly the required level, regardless of any outside influences. This is done by implementing a patented double feedback loop. This guarantees that the power impinging on the workpiece is at exactly the predetermined level. The pulse duration and beam quality are kept constant, as well. As is usual in the TruMicro Series, beam quality comes to a highly brilliant M2 of less than 1.3.
With mean power of 80 watts and short pulses at 800 femtoseconds, the TruMicro 5070 Femto Edition is among the most productive infrared femtosecond lasers on the market. It offers high throughput rates when machining components. The interplay of pulse energy, pulse shape and mean power makes it possible for the TruMicro 5070 Femto Edition to achieve significantly higher ablation rates for many materials. The short pulses bring about advantages when working temperature-sensitive materials such as composites and polymers. Thus the TruMicro 5070 Femto Edition promises to further broaden the applications which are suitable for cold processing. Less thermal energy is introduced into the material thanks to the narrower pulse widths. In this way, the higher mean power can be better applied to the workpiece. These properties predestine the TruMicro 5070 Femto Edition for demanding three-shift production in the microchip and electronics industry and in medical technology. Initial applications include drilling holes in circuit boards and processing polymers to be used as medical implants. Initial testing brought about impeccable results. Thus the TruMicro 5070 Femto Edition represents the perfect augmentation to the range of ultrashort pulse lasers now manufactured by TRUMPF.
