How about use a lens and make a divergent beam, then measure the power from a small area of that beam using a conventional laser power meter.
Are you sure? yes | no
that is why I bought Endurance lasers
because they tell the truth about their laser power...
I used to have 5.6watt and now I have 10 watt and it works great, cutting 3-4 mm of wood and plywood with one pass.
George, just made a measuments and post it on his blog page on EnduranceLasers.com site.

hi, you may check Endurancelasers.com blog and there we explain how to measure real power output/

From this :
https://en.wikipedia.org/wiki/Thermopile_laser_sensor
it seems that perhaps a Peltier element could be used to make a broadband laser power meter? I am not sure how would one calibrate it, but perhaps using a power resistor attached to it and supplying it with precise amount of electric power would do the trick.
