Information
Chapter 1 General Information
The IBP-YAG system is a precision instrument designed to measure critical parameters of High
Power Industrial type laser beams. As is indicated by the name it is optimized for 1064 nm YAG
lasers.
The IBP-YAG includes a measurement head for use on lasers of greater than 2 Watts and up to
4000 watts. The instrument is designed to measure collimated beams only, any focusing optics
must be removed before attempting any measurements.
There are three Models of IBP-YAG.
IBP-YAG for beam sizes from 1 to 4 millimeters.
IBP-YAG for beam sizes from 4 to 16 millimeters.
IBP-YAG for beam sizes from 8 to 30 millimeters.
The IBP-YAG measurement head is used in conjunction with the Spiricon Inc. software package
LBA-PC, which provides a complete, easy to use, highly graphical interface.
Each instrument is shipped with a serial number keyed setup file that contains specific calibration
information used by the software application.
Appendix C contains specific calibration information for your particular IBP-YAG unit.
1.1 How To Use This Manual
We suggest that you read this manual before setting up your IBP-YAG to become familiar with
the setup and use procedures. We also suggest that you read the software manual to become
familiar with the controls and the measurements provided.
Chapter 1 contains general Information and specifications of the IBP-YAG.
Chapter 2 contains setup and operating instructions.
Chapter 3 contains maintenance and storage information.
1.2 IBP System Components
The IBP-YAG system consists of the following components:
A measurement head that is placed in the laser beam’s path to attenuate the laser beam to a
measurable level and convert the laser’s energy profile into an electronic video signal. A water-
cooled beam dump absorbs the excess laser energy.
A Computer system with a Spiricon Inc. Frame Grabber Card and an LBA-PC software package
installed. The frame grabber card controls the Measurement head and digitizes the video signal.
An optional cart system with a built in heat exchanger and computer is available to make the
system more mobile.
If the system was purchased complete, the software and the frame grabber card will be installed in
the purchased computer. All files with specific hardware information will have been installed. The
IBP-YAG will have been connected and tested.
If the system was purchased to be used with an existing computer, the software and the frame
grabber card will need to be installed in the users computer before connecting the IPB-YAG.

Beam Dump: 4000 Watts average power
Operating the measurement head with incorrect attenuation settings may damage the video sensor
even though the input beam is below the damage threshold of the optics
1.3.3 Environmental
Storage Temperature: -30oC to +65oC (-22°F to 150°F)
Storage Humidity: 95% max. (non-condensing)
Note: When storage temperature may drop below 5°C, all cooling water must be removed
from the unit to prevent damage due to freezing.
————————————————————————
Operating Temperature: 10oC to 50oC (50°F to 122°F)
Operating Humidity: 90% max. (non-condensing)
Note: In high humidity conditions where the cooling water may be chilled to below the dew
point, dry air purge must be provided to prevent condensation from occurring inside the
unit.
1.3.4 Electrical Requirements
Measurement Head: 12VDC @ 500 mA
This power is supplied from the computer, through the camera cable.
1.3.5 Facilities Requirements
Purge Gas: (Optional) 5 liters/min (.18 STD cubic feet/min) of nitrogen or oil free air
with a dew point 10°C lower than the cooling water temperature.
Cooling Water: 3 liters/min (.8 gallon/min), 200 kPa (30 psi) max. See

1.5 Safety
The IBP-YAG is intended for use with high power YAG lasers. Precautions must be taken to
prevent accidental exposure to reflected and scattered beams. The safe use of high power lasers
requires that everyone near a laser be aware of the dangers involved.
1.5.1 Precautions for safe operation
•Keep the open beam path as short as possible. When practical, enclose the entire beam
path or set up shields to block reflections.
•Wear the appropriate protective eyewear when operating the laser.
•Do not set up the IBP-YAG or any optical components at eye level.
•Do not wear reflective jewelry or watches while operating this equipment to reduce the
possibility of causing accidental reflections.
•Establish a controlled area around the laser while in operation. Post prominent signs near
the laser operation area and limit access to individuals who are trained in laser safety.
•Use an IR detector or energy detector to verify that the laser is off before working on or
moving the equipment
•Keep the ambient light levels around the laser as high as practical. This will cause eye
pupils to constrict and reduce the possibility of hazardous eye exposure.

Setup and Operation
Chapter 2 Setup and Operation
2.1 Unpacking the equipment
The IBP-YAG has been carefully packed for shipment. If the container arrives damaged in any way,
please contact the shipper. Inspect each item as it is unpacked, looking for dents, scratches or other
damage. If damage is evident , immediately file a claim against the carrier and notify Spiricon.
2.1.1 Optional Cart system
If ordered, the cart system will be shipped separately and will include separate unpacking and setup
instructions.
2.2 Setting up the IBP-YAG
2.2.1 Frame Grabber and Software Setup
The IBP-YAG operates in conjunction with Spiricon’s LBA-PC software program and LBA-7xx frame
grabber. If the IBP-YAG was ordered with a computer system, the software and frame grabber card will
already be installed in the computer. If you are installing the frame grabber yourself, please refer to the
LBA-PC Operator’s Manual for instructions.
