What’s new – 2008
What Power Ranges Can I Measure?
From pW to kW
Cooling schemes
Convection cooled
Fan cooled
Water cooled
From 193 nm to 20 µm
18 July 2015
What if I want ENERGY?
Pyroelectric Technology
Crystal Lattice expands and contracts in response to laser
pulses
This creates an electrical signal that is proportional to
energy
18 July 2015
What Energy Ranges Can I Measure?
From ~10 pJ to 40 J
Up to 20,000 Hz Pulse Rate
From ms to fs pulse duration
ALL VALUES ARE INTERRELATED!
Need to carefully select correct head for your application
There IS a maximum power limit!
18 July 2015
Types of Pyroelectric Heads
Vary by Size of Detector Crystal

Why Perform Laser Beam Monitoring?
The Leading Indicator of a Degrading Laser is Deterioration of the
Beam Profile!
Quantitative Measurement of Laser Beam Characteristics
Record of Laser Beam Characteristics
Identify Problems Quickly
Reduce Scrap
Increase Productivity
18 July 2015
The most Productive way to get CONSISTENT performance
from your Laser is to Monitor the Beam Profile!

18 July 2015
Simple Beam Profiling Checklist
What is the average power of the laser?
What is the wavelength of the laser?
What is the width of the laser beam?
Pulsed or CW?
What quantitative information do I need to characterize the
beam? Beam width, shape, position, pointing stability)
