JPT YDFLP M Series User Manual page 8

★ for laser safety and long lifetime, when set ≥80ns, ≥400kHz, frequency will be limited at 400kHz,
*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 fiber laser when below the cut-off frequency value.
Below is the chart that shows the change between frequency and output:
