What is laser pulse width?

26 Mar , 2022

Pulse width is the duration of a light spot, expressed in units of time. The longer the pulse width, the longer the burning time; the shorter the pulse width, the smaller the thermal effect.


Pulse width is also a way of laser classification, such as:

Ultrafast laser means that the pulse width is picosecond (ps), femtosecond

(Fs) level and below.

The processing heat of the ultrafast laser is even smaller (cold light plus

Workers), even exquisite pictures can be carved on the match head case.


A narrow pulse width is an advantage. The pulse width is narrow and the thermal effect is low,

The better the processing effect; the pulse width is wide, the thermal effect is high, and the processing surface rougher.
