e2, as 7.38 times.When being measured with laser power meter, the power density at laser spot center is maximum.When the work(of laser
When rate is relatively low, it is not easy to which the damage threshold or the power meter using range bigger for reaching laser power meter will not cause to survey
Try the increase of cost.But during high-power laser test, it is easier to close to the damage threshold power of laser power meter, lead to power
Meter is damaged.
On the other hand, as the power of laser increases, the laser power meter for laser and directly tested is needed to be configured
Water cooling unit and larger power supply and power consumption are needed, the hidden danger such as leak, fire may be caused.
