The UF-20 from RMI Laser, LLC is a Yb-Doped Fiber Laser that operates at a wavelength of 1064 nm. It delivers a continuous wave output power of 20 W and has a peak power of 1 mJ. This Class IV or Class I laser has a pulse width of 100 ns (2 kHz - 200 kHz) and uses an F-theta lens with focal lengths of 100 mm, 163 mm, 254 mm, 330 mm & 420 mm. It has a plug-and-play rotary chuck adaptation and fiber laser controller that requires an AC supply voltage of 100 V - 240 V & consumes 5 A of current. This air-cooled laser is available in a module that measures 260 (L) mm x 149 (W) mm x 141 (H) mm & 431 (L) mm x 441 (W) mm x 132 (H) mm (controller) and is ideal for laser marking, etching & engraving applications.
