The world's first 20W high power 1064nm pulsed fibre laser engraver for use directly on frame laser engraving machines; professional-grade infrared laser module with up to 20W of optical power; fibre-optic conduction of energy with low loss; lightburn software support.
Main Features

1, High Power: The world's first 1064nm wavelength pulsed fibre-optic infrared laser module with optical power up to 20W, using Q-switched (photoelectric switch) main oscillator, high power fibre amplifier (MOPA) construction;

2, Multi-Material Application: MR20 fiber laser module can be applied to all daily metal (copper, iron, aluminium, zinc, silver, etc.) and plastic with high-speed fine engraving, as well as in black acrylic, leather, ceramics and rock engraving;

3, Metal Cutting: 20W laser output power and 0.03 * 0.06 ultra-fine spot allow MR20 to easily cut 0.2mm aluminium business card at a time, and cut 0.5mm brass sheet at multiple times;

4, High Adaptability: MR20 module can be quickly installed and adapted to all Atomstack brand laser engraving machine frame, and the working area can be expanded to 850*400mm or 850*800mm;

5, Customised Lightburn Control Board: In order to use with the LightBurn software, MR20 customised infrared laser module dedicated control board, so that you can set the laser power through the LightBurn, and through the knob to adjust the pulse frequency, greatly improving the simplicity of work;

6, Fibre-Optic Conduction: The use of fibre-optic conduction for energy transfer can greatly improve the efficiency of energy transfer and reduce energy loss;

7, Deep Cutting: 1064nm infrared laser is ideally suitable for deep engraving in the neat slate plane to give a relief effect;

8, Easy Focus: Easy double red light focusing method, 30 seconds to easily get the best focus;

9, Laser Rust Removal: MR20 1064nm wavelength laser, very suitable for removing the rust layer on the surface of metals, can quickly laser remove rust on the metal;
