NuQ™: 20W Fiber Marking Laser

NuQ

20W pulsed laser for marking, etching, & engraving

[NuQ image] The NuQ™ fiber laser is a 20W pulsed marker delivering 1 mJ pulse energy with a fast turn-on time (125 µs) and higher peak power (up to 10 kW) over a wide range of repetition rates (variable from 20–100 kHz), which maximizes production throughput and marking capability. With its single-mode beam quality, the NuQ laser can produce ultra-fine, crisp marks every time. The system design ensures zero bleed-through power when the gate signal is off, to prevent the appearance of ghost lines between marks, even on very sensitive materials. Complete with industry standard interfaces, the system is pumped by single-emitter diode lasers, which offer long lifetime and maintenance free operation.
