SPI Lasers redENERGY G4 M-Type 200W Laser Cleaning Parameters

Home - SPI Lasers spilasers.com (opens in new tab)

SPI reserves the M-Type label for the high-energy, long-pulse tier of its redENERGY G4 line, and this 200 W source earns it: 5 mJ pulses tunable out to 2000 ns, the profile SPI steers toward welding and cleaning rather than fine marking. That makes it a thermal-coupling descaler for mill-scale, pre-weld oxide, and thick coatings, shipped as a Southampton-built OEM module rather than a turnkey box.

OEM Laser Source Module

This is a laser source module sold to system integrators — not a complete laser cleaning machine. Specifications reflect the bare source only. End-user systems built on this module will vary in beam delivery, scan head, and enclosure.

Derived Parameters

Fluence at 2 mm spot0.159 J/cm²
Fluence at 5 mm spot0.0255 J/cm²
Overlap (cleaning)60–80%

Field spot diameter varies by scan head — 2 mm and 5 mm are representative values for handheld cleaning heads.

Derived from published specifications.
