SPI Lasers redENERGY G4 H-Type 70W Laser Cleaning Parameters
Sourcehttps://www.spilasers.com/
This H-Type trades single-mode fineness for coverage, packing High-Mode pulse energy into a broader spot to strip wide tracks of oxide and coating in fewer passes. A 3-2000 ns PulseTune waveform library matches damage threshold to each deposit, while air cooling and OEM-module packaging drop it into custom cleaning cells. It sits below SPI's 200W M-Type welding-grade sibling.

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 spot | 0.0398 J/cm² |
| Fluence at 5 mm spot | 0.00637 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.
