... first test with laser at 20 Watts, 100µs pulsing time on a black enamelled tile:

Tested with 80 Watt and 200µs pulse-time (50% PWM ratio) ... the mirrors survived, but this was no duration test -- with 40 Watts CW they will degrade, so I have to find the max. PWM values with the 120Watt-laser ...
