Strontium Lasers | QTekLaser

INTERNAL DRAFT — UNVERIFIED CONTENT. Strontium does not appear anywhere in the QTekLaser Applications dataset. Every transition below was drafted from the standard Sr cold-atom literature, not from your own product data, and every wavelength, role and availability call needs checking before release.

Strontium runs on a narrow-line cooling scheme and an optical clock transition, with a magic-wavelength lattice at 813 nm. The wavelengths below cover the blue MOT, the red MOT, the clock line, the triplet repumps and lattice and tweezer trapping.

Coverage across the strontium spectrum

Markers show the wavelengths a strontium experiment calls for. Bands beneath the axis show where QTekLaser™ generates light — by second-harmonic generation, sum-frequency generation, or directly from a single-frequency amplifier.

Review notes

Nothing on this page is verified. Strontium is absent from the Applications dataset that drives every other species page. Treat the whole table as a proposal.
689 nm and 698 nm both fall inside the SFG band — the narrow-line MOT and the clock transition. If the SFG platform really can reach them with useful linewidth, that is the strongest Sr argument you have and deserves its own product page.
707 nm misses the SFG band by 1 nm and 813 nm — the magic-wavelength lattice — falls in the 805–822 nm gap. Both are standard Sr requirements. Confirm whether the bands can stretch.
The 1530 nm row is speculative and should probably be deleted unless you have a specific Sr use for it.
Decide whether Sr belongs in the Applications dataset too, so this page and the Overview agree.
