Widely tunable high power laser
In order to achieve a laser covering multiple wavelengths from the ground state to the excited state of rubidium atoms, Frequency-Centric 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.
Real photos | wavelength | power | Solution Overview | Features |
| 480nm | 0.04-0.8W | The thulium-doped fiber DFB produces a high-power 881nm laser after amplification and single-pass frequency doubling. The 1057nm wide-tuned external cavity semiconductor laser passes through the ytterbium-doped fiber amplifier and is frequency-harmonic with the 881nm laser to produce a high-power laser output covering 479-484nm. |
|
| 297nm | 0.3-1W | The scheme based on sum frequency produces high-power 594nm laser, in which one sum frequency seed is a widely tuned external cavity semiconductor laser, which is then frequency doubled to produce high-power 297nm laser |

Frequency Stabilization and Other Accessories
The excitation of the Rydberg state of rubidium 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. Frequency Accuracy Laser has also introduced corresponding solutions such as frequency stabilization.
