It can be seen that the existing fiber laser improves the beam quality of the laser beam through the laser amplifier, but the improved beam quality parameter is a fixed value and cannot be adjusted any more.
It is therefore desirable to provide a laser beam quality parameter adjustment device and a fiber laser that can adjust the beam quality of the laser beam during use.
