Widely tunable high power laser
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 semiconductor lasers and the high power characteristics of fiber amplifiers.

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.
