F1 Ultra is a dual laser. It has 20W fiber and 20W galvo blue diode laser. F1 Ultra can engrave Almost ALL Common Materials in daily life. Diode lasers perform best on wood, acrylic, leather, slate, glass, ceramic, etc., while fiber lasers can engrave clearly on all-metals(stainless steel, aluminum, gold, silver, iron, platinum) and plastic.

And yes, F1 Ultra is a true fiber. The F1 Ultra uses an IR (infrared laser) as its laser source, while the fiber (diode-pumped fiber laser) serves as the gain medium. Both are essential components for generating laser light.

Each laser light is produced when the laser source strikes the gain medium, which then amplifies the intensity of the laser beam. Unlike the S1 & F1 models and other common IR lasers on the market that use DPSS (diode-pumped solid-state laser) as the gain medium, the F1 Ultra leverages a fiber gain medium to maximize laser power. This results in deeper engraving and cutting at the same power level.

F1 Ultra can deeply engrave, emboss and even cut metal. F1 Ultra can cut 0.4mm brass, 0.3mm stainless steel and 0.2mm aluminum sheet.

F1 Ultra will be compatible with RA2 Pro. For the smoke purifier, we recommend using the SafetyPro™ AP2 Air Purifier for its larger filters and longer purification lifespan.

F1 Ultra：

Most Efficient Batch Engraving on almost all materials: F1 Ultra has both 20W Fiber and 20W Diode Laser with its super speed 10000mm/s, 220*220mm engraving area and auto streamline™ production
Versatile Jewelry Making: F1 Ultra has 20W fiber, which can do deep metal engraving, embossing, thin metal cutting

F1:

Craft Fair Must-Have: F1 is the mini size of F1 Ultra, Its compact size makes it portable to bring it to craft fair. With its 2W Infrared laser with 10W diode laser and 4000mm/s, F1 can do customize engraving on almost anything quickly onsite.
DIY Starter: F1 is fun to play and has minimal learning curve, it also has relatively lower price to purchase

xTool F1 Ultra has ultra HD resolution, same as xTool F1. Its Fiber has 0.03*0.03mm compression spot on fiber, and its diode galvo laser has 0.08*0.1mm compression spot.

There is no need to change the field lens of F1 Ultra for several reasons: First, F1 Ultra has the largest working area in desktop fiber. Second, F1 Ultra uses microbeam technology to restore the details of every image, even in the corner of the working area. Third, the field lens is well protected inside F1 Ultra, as we planned an airflow path that (with a built-in fan) blows away all dust generated through engraving outside the machine.

F1 Ultra:

It is the king of desktop laser engraving, and can engrave almost all materials at the fastest speed, most detailed resolution and versatile engraving result.

P2:

King of the desktop laser Cutter, it can cut acrylic up to 20mm thick in all colors, as well as 18mm thick black walnut. It also features a user-friendly 16MP Dual HD Camera.

Yes, F1 Ultra can adjust from 30 to 60kHz.
