Yb:YAG lasers typically operate at 1030 nm and are pumped around 940 nm. Why choose Yb:YAG instead of Nd:YAG? Yb:YAG offers higher efficiency and lower thermal load due to its low quantum defect, making it ideal for high-power and ultrafast lasers. What dopant concentrations are available? Standard Yb:YAG concentrations range from 3–10 at.%. Custom concentrations are available. Do you offer custom sizes or shapes? Yes. Rods, slabs, discs, thin-disk formats, and custom geometries are supported. Are AR coatings available? Yes. AR coatings at 940 nm (pump) and 1030 nm (laser) are available, including dual-band designs. What is the typical lead time? In-stock items ship in 1–2 business days. Custom orders typically require 2–3 weeks.
