Coverage across the cesium spectrum

Markers show the wavelengths a cesium 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

The Cs D2 line at 852 nm is not a catalogue product — it is configured within the SFG band. Consider whether it warrants a dedicated 852 nm product page, as 780 nm has for Rb.
1005 nm sits 7 nm below the stated Yb band (1012–1080 nm). Confirm whether the band can be extended or the row should be dropped.
319 nm and 459 nm are listed as custom on the strength of the “260–2040 nm achievable” claim.
SFG powers shown are the 20 W family maximum, not measured figures at 825 / 852 / 895 nm.
