YLR-U Series

New Generation of Super Grade Mid Power 1 μm Lasers

Introducing the YLR-U Series, the next generation of fiber laser technology. These ultra-compact lasers deliver unparalleled results in the highest power to volume ratio of any fiber laser in the industry. The YLR-U is powerful enough to handle typical material processing applications including welding, cutting and drilling metals. The exclusive High Peak Power option supports repeatable piercing and drilling of thick materials along with welding and cutting of highly reflective materials.


The World’s Smallest kW-class Fiber Lasers

YLR-U Series are the smallest kW-class CW ytterbium fiber lasers in the industry that offer unmatched performance in record-breaking, ultra-compact form factors with the highest power to volume ratios.

The new generation of IPG flagship YLR fiber lasers takes their legendary performance to a whole new level. The unrivaled combination of high CW power, exclusive High Peak Power option, ideal beam quality, unsurpassed reliability and industry-leading wall-plug efficiency delivers the best value on the market.

YLR-U Series incorporates the latest advancements in IPG world-leading industrial pump diode packaging technology and are the only hermetically sealed mid-power lasers on the market that can operate in extremely high humidity environments up to 90% relative humidity. Remote control options include Analog, RS-232 or Ethernet, and built-in self-diagnostics with internet connectivity. The user-friendly rack mount configuration is the most cost effective and adaptable solution for integration into Industry 4.0, Smart Manufacturing production lines.

YLR-U lasers are ideal for a wide range of metal cutting, welding and drilling applications. The High Peak Power Option enables fast clean repeatable piercing and drilling in thicker materials, precision quality cutting, additional pulsed welding capabilities, and cutting and welding of highly reflective metals. YLR-U lasers improved piercing quality enables shorter lead-ins with denser part nesting that reduces overall material waste. Available exclusively from IPG, the High Peak Power Option provides improved process quality and speed, increased overall throughput, while saving material, time and operating costs.
