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
 9 mm to 100 mm diameter
 Vary by Type of Coating
 Metallic
 BroadBand
 Some Have Diffusers or Splitters
 Extends power range
18 July 2015
What about High Power Energy?
RP Heads- The Only Solution
 Patented Design Allows High Energy Measurement at High
Power

18 July 2015
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!

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)
