fiber laser source pulse width introduce

Fiber laser source pulse width introduce. Usually Fiber laser source pulse width is always fix.  Like Raycus is randam fix from 80-130ns.

But Do you know what does pulse width mean? Pulse width means how long  the peak power last. If pulse width is high. Then it means the peak power can last long.

But if smaller pulse width. Then it means shorter time peak power last.

So for same power laser source. If the pulse width is larger. Then it will has stronger energy to  engrave. Like Mopa laser source from JPT. The pulse width can be adjust.

Width is not fix at all. From 2ns to 250ns, you can choose parameter.
