*For laser safety and long lifetime concern, when pulse width set ≥80ns, frequency range will be
limited at 400kHz.
* The laser will have expected output power when working above the cut-off frequency. When
working below the cut-off frequency, the power will drop accordingly to maintain the output
peak power. Below chart shows the relationship between frequency and output power:
