Coherent Launches Germanium-Free Modulator for High-Speed CO₂ Laser Drilling

  • Coherent introduced a germanium-free electro-optic modulator (EOM) for high-speed CO₂ laser via drilling in semiconductor manufacturing.
  • The EOM delivers sub-microsecond pulse generation at up to 300W, with a 1,000W version in alpha testing.
  • Eliminates reliance on scarce germanium while offering faster switching and higher power handling than traditional acousto-optic modulators (AOMs).
  • Product available for order now; pairs seamlessly with Coherent CO₂ lasers and F-Theta lenses.

Coherent’s new EOM addresses critical supply-chain constraints in semiconductor manufacturing by eliminating dependence on germanium, a scarce material. The product launch underscores the growing importance of material innovation in photonics, particularly as laser-based processes become more integral to advanced chip production.
