Hi Jeshua,
I spent a number of years feeding a Trumpf 4kW industrial laser. It has been a
while but I'll dump what I know.
1. The output of the laser beam changes width as it exits the laser tube. The
industrial machines use a patented fixed length beam delivery system. Think of
this as a

Most lasers using PWM control require a frequency between 5Khz and 25Khz,
then how long the signal
