Table 5 Threshold Frequency（kHz）of LP series laser
Pulse width(ns) 30-LP2+-L1 30-LP1+-S 20-LP1+-S 20-RE+-S 60-LP1+-L1
200 30khz 37khz 30khz 30Khz 50Khz
The cut-off frequency is the minimum frequency that the laser can be operated with maximum
peak power and average power. Please operate the fiber laser at frequency higher than the cut-off
frequency.
*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 ：
Figure 3 Cut-off Frequency & Output power relationship charts
* Remarks:
Threshold frequency = Cut-off frequency, of which the definition are the same.
