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.
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.
