HighLight™ FL Series Pulsed

High Power Pulsed Fiber Lasers – kW Power and Shortest Pulses Combined with Highest Beam Quality

High power pulsed fiber lasers complement Coherent-Rofin’s high power fiber laser offering. The HighLight FL1000P is a 1 kW pulsed fiber laser that offers the highest beam quality currently available at this power level, thus enabling high throughput, precision ablation for a variety of industrial and solar applications.

The Coherent-Rofin HighLight FL-P Series is designed to deliver exceptional reliability and high uptime in demanding, multi-shift industrial environments and its compact footprint is virtually predestined for integration into existing machining workstations. It uses field-proven components as employed in the Company’s standard, CW fiber laser products: passive cooled T-bar pumping modules tolerating single emitter faults, power supplies and the RCU control unit. The control unit offers numerous monitoring tasks and e-service capability. 

The HighLight FL1000P lasers deliver a maximum pulse energy of 100 mJ, at pulse widths between 10 ns and 100 ns, and with repetition rates ranging from 10 kHz to 30 kHz. A beam parameter product of typical 20 mm x mrad (for a 400 μm, round core output fiber) enables this power to be effectively concentrated into small focused spot sizes. 

The unique combination high average power, high pulse energy and superior beam quality makes the HighLight FL1000P an ideal laser source for ablation, surface cleaning, and precision material and coating removal in a range of applications. These include AlSi removal from tailored blanks prior to welding, edge deletion for thin film (a-Si, CdTe, CIGS) solar cells, cleaning of molds, aerospace components and other precision parts, as well as other surface cleaning, activation and structuring uses. 

In addition, a scanner processing solution package is optionally available enabling simple implementation of scanner-based applications.
