Every wavelength a rubidium experiment needs — cooling and imaging on the D2 line, gray molasses and Raman control on D1, lattice and tweezer trapping, and two-photon Rydberg excitation — from one single-frequency, PM, all-fiber platform.

Coverage across the rubidium spectrum

Markers show the wavelengths a rubidium 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.

Where the D-line light comes from

The rubidium D lines are reached by frequency-doubling a telecom-band seed. That is why the 780 nm and 795 nm systems inherit the linewidth and noise of a single-frequency fiber laser rather than a diode.

Review notes

297 nm and 420 nm are listed as custom on the strength of the “260–2040 nm achievable” claim. Confirm whether to advertise them, and at what power.
810 nm falls between the SHG band (765–805 nm) and the SFG band (822–900 nm).
1529 nm sits 1 nm below the stated Er band (1530–1610 nm) — either the band edge or this row needs adjusting.
840 / 852 / 1013 nm powers are family maxima, not measured figures at those wavelengths.
The Applications dataset tags 852 nm as both Rb and Cs. 852 nm is the Cs D2 line — confirm the Rb tag is intended.
