Ytterbium spans the widest wavelength range of any species we serve — from deep-UV Rydberg excitation at 259 nm to 1064 nm lattices. Sixteen transitions, covering the blue MOT, narrow-line cooling, the clock transition, tweezer-array addressing and qubit shelving.

Review notes

578 nm — the Yb clock transition — falls in the gap between the SHG band (506–540 nm) and the SFG band (609–706 nm). This is the most-asked-for Yb wavelength after 399 nm; decide how to answer it before publishing.
497 nm sits 9 nm below the SHG band edge. Confirm whether the band can stretch.
259 nm is 1 nm inside the “260–2040 nm achievable” claim as written — the claim and this row disagree.
455–485 nm is a range rather than a line; confirm what is actually offered across it.
Yb is the strongest species page by catalogue coverage — six of sixteen wavelengths are stock products.
