Embodiment 1
[0030] Such as figure 1 As shown, a non-phase measurement automatic synchronization method for passive coherent combining lasers, including the following steps:
[0031] Step 1. Simultaneously collect multiple laser optical signals and convert the laser optical signals into laser electrical signals, including but not limited to photodiodes, photoelectric sensors, etc. The main purpose is to convert optical signals into electrical signals for subsequent acquisition of optical signals. The timing of the signal. Step 1 also includes subsequent processing of converting the optical signal into an electrical signal, such as noise reduction, filtering, amplification, etc.;
[0032] Use a single-chip microcomputer or other processors to collect multiple laser electrical signals. The first acquired laser electrical signal is set as the reference laser electrical signal, and the other laser electrical signals are used as the laser electrical signals to be corrected. The ideal synchroni...
Embodiment 2
[0046] Such as figure 2 As shown, an automatic synchronization method includes the following steps:
[0047] Step 1 is the same as Step 1 in Example 1.
[0048] Step 2, replacing the laser power drive signal to be corrected and the reference laser power drive signal in step 2 of embodiment 1 with the Q-switched pulse signal to be corrected and the reference Q-switched pulse signal respectively,
[0049] In addition, in step 2.3, the adjusted Q-switched pulse signal to be corrected and the reference Q-switched pulse signal respectively drive the corresponding Q-switched crystal of the laser to be corrected and the Q-switched crystal of the reference laser.
[0050] Algorithms are used to correct the Q-modulated pulse signal. In some Q-switched lasers, although the driving pulses generated by the driving power supply are not synchronized, due to the existence of the Q-switched crystal, the synchronization of the output laser can still be controlled by controlling the opening ...
