The MOPA laser marking machine is a fiber laser marking system built on master oscillator power amplifier technology. A master oscillator generates the laser seed source, and a power amplifier boosts the laser energy, which allows pulse parameters such as frequency and pulse width to be adjusted independently for more precise control of the marking result.

The system operates at a 1064 nm wavelength with output power options of 20 W, 30 W and 60 W. Marking speed reaches 7000 mm/s, repeatability is ±0.002, and the minimum line width is 0.001 mm, with light beam quality below 1.5. The frequency range is 1–4000 kHz and the pulse width is adjustable from 2 to 500 ns. Marking content includes graphics, characters, barcodes and QR codes.

Standard marking areas are 100×100 mm, 200×200 mm and 300×300 mm, with customization available on request. The machine marks both metals and non-metals; the supplied samples show color marking on stainless steel parts as well as QR code and data-matrix marking on metal surfaces. Power supply is AC 220V/110V ±10%, 50Hz/60Hz with power consumption below 1 kW, and cooling is air-based. Optional cabinets and fixtures — including an XY worktable, rotary chucks and a rotary table — are available for different production setups.
