Embodiment 3
[0049] Such as Figure 7 As shown, in addition to the structure of embodiment 2, the device for generating a new wavelength laser with ultrashort laser pulses with different sum frequencies provided in this embodiment also includes an electronic computer 7, which is electrically connected to a translation stage 9, with To control the movement of the translation stage 9. The electronic computer 7 constantly monitors the relative cavity length changes of the two lasers. It accurately controls the displacement of the translation stage 9 to compensate for the changes in the laser cavity length caused by changes in the external environment and other factors. Once the synchronization is started, the two lasers will always be maintained. Synchronous, there is always a stable sum frequency laser output.
[0050] The real-time control of the electronic computer is added to improve the synchronization maintenance time. If there is no electronic computer for real-time control, the synchroniz...
