OK, im not entirely new to lasers, just CO2. Im building a CNC laser table.
I have a Laser Engineering M-55 sealed tube with the specs here

My Power Supply is a Universal Voltronics 700W LRC specs here

I am building my own controls based on a PIC.
My questions are:
Should I run in pulsed mode?
What frequency should I run it at, or make it variable freq. ?
Should I control power output with duty cycle?
I got a little control board going playing around with different frequencies and duties, but it just doesnt seem quite right.
Any help on how to implement pulsing would be much appreciated.
Thanks!!!
