YLPN-S Nano Pulse Fiber Lasers offer variable pulse durations in 25-100 nanosecond range. The laser power can be adjusted in a wide range of pulse repetition rates independent of the pulse energy. Average output powers are up to 3 kW and pulse repetition rates vary from 2 to 300 kHz. Integrated beam switch option enables processing multiple workstations in time or energy sharing modes. Housed in rugged sealed cabinets, these compact efficient maintenance-free systems are designed to operate in harsh industrial manufacturing environments. Powerful YLPN-S lasers are optimized for high throughput surface treatment applications such as paint stripping, coating removal, surface cleaning and texturing.

Managing Low Adhesion Railways
Anyone who has traveled by trains in the fall is familiar with delays caused by rail track contamination by fallen leaves. Wet leaves form a greasy film that continues to build up over time. The loss of grip between train wheels and rails and slipping of the train wheels make acceleration or even maintaining a constant speed more difficult, resulting in lower commercal train speed and an increased energy consumption. Furthermore, longer braking distances may lead to dangerous accidents, requiring lowering the maximum train speed. Various solutions to this problem have been tried. The goal is removing the greasy layer while not interfering with the rail traffic. The rail cleaning must be done at a reasonable speed, from 40 km/h to 100 km/h and more. Rail cleaning must be a simple and scalable process. This is exactly what Laser Precision Solutions from the Netherlands implemented with high-power pulsed fiber lasers from IPG Photonics as a result of a six-year railroad cleaning project. The breakthrough came with the availability of compact pulsed fiber lasers with an average power of 1 kW which allowed achieving desired cleaning speeds.
The rail cleaning module is attached to the railroad car, while the the fiber laser is located in the car. The lubricating film is removed with great precision without affecting the rails. These cleaning trains are increasingly used in the USA. The aim is to reach cleaning speed of 100 km/h, which cannot be realized with alternative technologies such as water jet cleaning.
