Chapter 5 Operation Guide
（1）Set the pulse width, pulse repetition rate, and power according to
different materials and marking purpose.
（2）Cut-off power frequency : If the pulse frequency is lower than the
cut-off power frequency the exact maximum output power will be also
lower than that at the cut-off power frequency. But if the frequency is
higher than the cut-off power frequency, the maximum output power
is the same with that at the cut-off power frequency. For example, the
maximum output power is 20W if the laser is set with 200ns/45KHz/100%,
while the maximum output power is drop to 10W if the laser is set with
200ns/23KHz/100%, and the maximum output power is also 20W if the
laser is set with 200ns/46KHz/100%.
