Embodiment 1

[0054] The composition of the laser is generally as follows figure 1 shown. At present, when marking with a laser, the processing control system first generates the first driving signal and the second driving signal according to the PSO signal, and then sends the first driving signal and the second driving signal to the laser control board.

[0055] After receiving the first driving signal and the second driving signal, the laser control board first drives the first modulator according to the first driving signal to select the frequency of the seed optical signal to obtain the modulated laser signal. At this time, the frequency of the modulated laser signal generally decreases It is tens of kHz to several MHz, and the frequency of the seed optical signal is generally 30-50MHz. Therefore, the frequency of the modulated laser signal is reduced compared to the frequency of the seed light.

[0056] Since the frequency of the modulated laser signal drops, if the first frequency o...

Description

technical field [0001] The present application belongs to the field of lasers, and in particular relates to a control method and device for laser signals, a laser and a readable storage medium. Background technique [0002] With the development of science and technology, the performance of lasers is getting better and better, and the application of lasers is becoming more and more extensive. For example, lasers are used for marking. [0003] At present, when marking with a laser, the position synchronization mode (Position Synchronized Output, PSO) is generally used, that is, when a target position is reached, a PSO signal is sent to make the laser emit light. However, at present, since the frequency of the first driving signal controlling the first modulator is consistent with the frequency of the PSO signal, the power of the laser signal after passing through the first modulator is relatively low, while the power of the pump light in the amplifier is generally fixed At t...
