Very often, a laser spec gives a range of values for various parameters – “Power from X to Y, Beam Diameter from…to…,” and so on. Now we need to measure the laser beam and we need to choose the right sensor. Let’s say the laser spec says:
- Pulse energy: 1mJ – 100J
- Pulse rate: 1Hz – 1KHz
We might be cautious and look for a sensor that can handle all of those numbers...but wait. 100J pulses at 1KHz – that...
