Industrial 19" rack-integratable ultra-stable lasers with low phase noise are a key enabling technology for future quantum technologies. These technologies rely on addressing narrow-linewidth clock transitions and therefore require laser systems with sub-Hz linewidth and high stability even in out-of-the-lab conditions. We at TOPTICA want to provide you with the necessary ultra-stable sub-Hz laser system. (so that you can focus on your research). Our ultra-stable lasers yield the highest frequency stability far beyond 1-second integration time to drive the very narrow atomic clock transitions in neutral atoms like Yb and Sr and ions like Yb+, Sr+, Ca+, and Ba+.
TOPTICA's clock laser systems are diode lasers whose linewidth is reduced to less than 1 Hz via frequency stabilization to high-finesse optical ULE cavities. For wavelengths between 670 nm and 1762 nm, TOPTICA’s MDL pro or amplified MTA pro lasers are directly locked to the ULE cavity. For wavelengths below 670 nm, the fundamental laser light is first stabilized in the ULE cavity, and then frequency-doubled via second harmonic generation (SHG). The MCLS' robust design, excellent passive shielding, and active vibration compensation make it resilient to external acoustic and seismic vibrations. A high-end temperature stabilization system guarantees the highest stability towards temperature fluctuations. The complete system is controlled with one interface, which is hosted by the DLC pro and can be accessed with the PC GUI TOPAS.
