Industrial-grade ultra-stable lasers with low phase noise enable advanced quantum technologies that rely on narrow-linewidth clock transitions and therefore require laser systems with sub-Hz linewidth and high stability even in out-of-the-lab conditions. TOPTICA’s ultra-stable “CLS” lasers yield the highest frequency stability far beyond 1-second integration time to drive very narrow optical transitions in atoms like Yb, Sr, or ions like Yb+, Sr+, Ca+, and Ba+, or even in Th nuclei.
TOPTICA's CLS usually uses external cavity diode lasers whose linewidth is reduced to less than 1 Hz via frequency stabilization to high-finesse optical ULE cavities. For wavelengths below ~ 660 nm, the fundamental laser at a higher wavelength is first stabilized in the ULE cavity and then frequency converted (SHG/FHG). Amplification is possible via ALS-IR low-noise fiber amplifiers or TA pro tapered amplifiers. Robust design, excellent passive shielding, and active vibration compensation make the CLS resilient to external acoustic and seismic vibrations. A high-end temperature stabilization system guarantees the highest stability against temperature fluctuations. The complete system is controlled with one DLC Pro-hosted interface and can be accessed with the PC GUI TOPAS.
