Frequently Asked Questions

What is the lead time for custom laser crystals?

Standard products ship within 1–2 weeks. Custom-doped or bonded crystals typically take 4–6 weeks depending on complexity.

Do you offer coating services?

Yes, we provide AR, HR, and partial coatings for laser rods, windows, and substrates across UV to IR ranges.

Are your scintillation crystals hygroscopic?

Most of our scintillators (Ce:GAGG, Ce:YAG, LYSO) are non-hygroscopic. Halide types may require encapsulation.

Can I request material test reports?

Absolutely. We provide full certification including doping concentration, absorption spectra, and dimensional reports.
