Why KM diode laser machines more powerful than others with same power ?

Why KM diode laser machines more powerful than others with same power ? 

Such as our 1200W model real output even higher than 1600W of other brand machine .

Because our duty cycle is higher , ours real pulse width is 300ms , others real pulse width is 200ms . But how to distinguish real duty cycle of machine ? 

Only use the most famous brand Israel VEGA energy meter to test real output per pulse . Because even you write 300ms in software treatment interface

 that may fake hidden energy . Or you use a simple Chinese brand energy matter to test a high fake data energy . Those all useless information for useful

 performance machine .
