When to use Thermal Offset in Laser Power Measurement
You might think – as I used do – that offset is pretty simple.
Before measuring your laser, see if the meter displays a value.
If not, great. If it does, that’s unwanted, so press “Offset.”
However, the truth is there are several different kinds of offset and it’s important to understand a little bit about how thermal sensors work in order to know when to hit that offset button and when to resist.

Scatter Shields: Reducing Back-Reflected Power from High Power Sensors
When measuring very high power laser beams, even the few percent of the beam normally back-scattered from the sensor can be a problem. Ophir now offers Scatter Shields as accessories for our high power laser sensors; these can be mounted on the front flange of the sensors to reduce the backscatter by about 70%.

Focus shift monitoring of high power lasers
Measuring the focal spot of a high power laser is challenging, at best.
The main issue is that when a high power laser is focused down to a small point, the power density can be extremely high, typically high enough to damage any sort of measurement equipment you would use.
The solution?

Does damage threshold depend on power level?
Does power density damage threshold really change with power? Shouldn’t it remain the same throughout the whole power range? In this video you’ll learn why the specified damage threshold does indeed depend on the power level, and not just on power density.
