Precilasers' narrow linewidth high-power lasers cover wavelengths from ultraviolet to infrared, and can provide lasers of various wavelengths for the excitation of Rydberg atoms, realizing quantum computing based on Rydberg atoms and ytterbium atomic optical clocks. Quantum computing based on ytterbium atoms requires narrow linewidth lasers of various wavelengths for cooling, trapping, and manipulating atoms, as shown in the figure below [1].

Narrow linewidth lasers for quantum state manipulation and excitation of atoms
In order to achieve a laser covering multiple wavelengths from the ground state to the excited state of cesium atoms, Precilasers has launched a widely tunable laser that perfectly combines the wide tuning characteristics of external cavity diode lasers and the high power characteristics of fiber amplifiers.

The 1555nm fixed external cavity semiconductor laser seed passes through an erbium-doped fiber amplifier and then frequency-doubles with the 987nm laser to produce a 604nm laser. After cavity frequency doubling, a high-power 302nm laser is produced. |

Frequency Stabilization and Other Accessories
The excitation of the Rydberg state of cesium atoms requires that the laser wavelength be accurately aligned with the transition spectrum of the atom and that the wavelength be kept stable for a long time. Precilasers has also launched corresponding frequency stabilization solutions.
