For safety concern, when pulse width ≥80ns , frequency ≥400 kHz, input and output
frequency is as shown in the figure below:
*Above the cut-off Frequency value is the fiber laser full power output range, oppositely,
below the cut-off frequency value is the cut-off power output range. That means the fiber
laser will reduce the output power to protect the machine when below the cut-off frequency
value. Below is the charts that showed the change between frequency and output ：
