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 strontium Rydberg atoms and strontium atomic optical clocks. Quantum computing based on strontium atoms Rydberg requires narrow linewidth lasers of various wavelengths for cooling, trapping and manipulating atoms, as shown in the following figure [1]

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.
