IPG Photonics’ new ULPN-R Series ultraviolet nanosecond fiber lasers provide high peak power with scalable average output power up to 30 W, 1.5 ns pulse duration at full operational repetition rate range of 10 - 600 kHz. The all fiber format allows for the adjustment of pulse energy and/or pulse repetition rate without affecting any of the output beam parameters. IPG’s novel fiber laser is much more efficient and compact than conventional lasers now on the market, and is ideal for applications in the solar/photovoltaic arena, resistor trimming and marking of transparent materials. The short wavelength, short pulse duration and high peak power result in very small heat affected zone.
