Eolite Systems has added a new picosecond laser

 Eolite Systems has added a new picosecond laser, the Hegoa, to its rod-type fiber laser family.

The high-power pulsed fiber laser is suitable for use in a wide range of fine micromachining applications, including cutting, engraving, thin-film ablation, wafer processing, microdrilling and scribing in industrial fields such as photovoltaics, semiconductors, microelectronics, LEDs and flat panel display processing. It has a rugged optomechanical design for long-lifetime operation.

 The fiber laser operates at 1030 (infrared), 515 (green) or 343 (ultraviolet) nm, with 30-ps pulse duration from 0.5 up to 6 MHz. Based on proprietary and scalable rod-type fiber technology, it reaches high average power of up to 60 W at 1030 nm with beam quality of M² <1.3.

 The infrared model delivers 30-W average power and maximum energy/pulse of 100 µJ. The green model delivers 15 W of average power and maximum energy/pulse of 30 µJ, and the ultraviolet type delivers 7 W of average power and maximum energy/pulse of 15 µJ.

 General features include linear polarization and a repetition rate from 200 kHz to 10 MHz.
