YLS-U and YLS-CUT, 1-25 kW

Fiber Laser for Metal Cutting

YLS-CUT and YLS-U lasers have been developed specifically for demanding cutting applications. Supplied in the smallest form factor available on the market, these lasers can be easily integrated within cutting machines. Lasers are packaged in a hermetically sealed cabinet containing an internal dryer, enabling the laser to be used in the harshest of production environments. The YLS-CUT and YLS-U incorporate the latest IPG technical improvements in the design of diode modules, fiber blocks, digital power supplies and digital control electronics, resulting in unparalleled reliability and increased control flexibility, stability and precision. The new control system allows integrated control of both laser and process subsystem.


IPG’s family of kW class YLS-CUT lasers has been specifically designed for high performance in harsh cutting environments. The YLS-CUT series features a super compact design with the laser housed in an hermetically sealed cabinet. A dehumidifier is installed within the cabinet to ensure optimal internal humidity. Due to continuous design improvements, the industry-leading wall-plug efficiency has reached over 40% in 2015. The electrical cost savings add up to many tens of thousands of dollars over lifetime of a laser. Hot redundancy ensures 100% up time with no change in power, record reliability and maintenance-free operation. The CUT series lasers are available up to 25 kW output power with a wide variety of fiber delivery options, starting at 50 μm core diameter.

YLS-U is the latest super-compact hermetic cabinet packaging of kW-class lasers in power 1-10 kW range incorporating all of the features and technology advancements of YLS-CUT series. YLS-U Series lasers are also available with the High Peak Power (HPP) option enabling faster and cleaner piercing, increased quality of fine feature cutting and denser part nesting.
