Glass and Ceramic Micromachining with M8 Fiber Lasers
Fine-feature processing on brittle materials, micro-holes, scribing and precision marking on glass, alumina ceramic and similar substrates, with the minimal heat damage that delicate parts demand.
Short answer: glass and ceramic micromachining uses M8 fiber lasers to create fine features, marks and micro-holes on brittle materials without the cracking and chipping that mechanical tools and longer-pulse lasers cause. The M8 short-pulse architecture limits heat spread, which is what protects the substrate. Marking and fine work start at the 20W and 50W M8; actual drilling needs the 120W M8.
What micromachining covers
Micromachining is precision removal and marking at small scale, where the material is unforgiving. Glass and technical ceramics such as alumina are brittle and crack easily, so the process has to be gentle thermally while still removing material accurately.
- Precision marking on alumina ceramic substrates, dental ceramics and glass.
- Fine scribing and feature definition on brittle substrates.
- Micro-holes in glass at the higher-power tier.
- Brittle-material processing for electronics, sensors and labware.
Matching the M8 tier to the work
This is where the M8 power tiers split cleanly by job:
- 20W M8 (USD 3,300): the entry into M8 architecture for small-lot ceramic and glass marking and fine work, air-cooled and benchtop friendly.
- 50W M8 (USD 4,800): the mid tier for production glass and ceramic marking and etching.
- 120W M8 (USD 10,500): adds genuine glass drilling and the highest peak power for demanding brittle-material work.
Pick the tier by whether you need marking and fine features (20 to 50W M8) or actual drilling (120W M8). For surface marking on glass with zero heat-affected zone, the UV laser is an alternative; for drilling specifically, see the glass drilling laser page.

Frequently asked questions
What is the difference between glass marking and glass micromachining?
Marking changes the surface appearance; micromachining removes material to create fine features or holes. Marking and fine work run on the 20W and 50W M8, while micro-hole drilling needs the higher peak power of the 120W M8.
Can M8 lasers process alumina ceramic?
Yes. Alumina ceramic precision marking and brittle-material processing are core M8 use cases; the short-pulse architecture limits heat spread so the brittle substrate does not crack.
Which M8 tier do I need?
For marking and fine features on glass or ceramic, the 20W or 50W M8. For actual micro-hole drilling in glass, the 120W M8. Match the tier to whether you are marking or removing material.
Why not use a standard fiber laser?
A standard M7 fiber laser has a longer pulse that puts too much heat into glass and ceramic, cracking them. The M8 short pulse is what makes clean brittle-material processing possible.
