An integrated laser beam measurement/profiler system for pulsed and CW lasers. System contains an SP620 camera with variable attenuator for beam profiling. A thermopile power head for power measurement and a high speed photodiode for temporal pulse width measurement. Includes BeamGage Standard beam profiling software, and a USBI power meter w/StarLab software. An optional USB digital oscilloscope is available for temporal measurement of pulsed lasers, order p/n SPE10008. Or a standard laboratory oscilloscope can be used.
Diagnostic Capabilities: Spatial Beam Profile
The Beam Cube shows you the intensity profile of your beam in real time and allows you to adjust your laser resonator and beam delivery optical system for optimum beam quality on line. You can also measure the cross section at any point as shown. The illustration shows the intensity distribution of a pulsed Nd:YAG laser where the X and Y profiles are taken at the cursor lines which can be placed anywhere on the beam. This data can be saved, brought back and manipulated at any time so you can compare the present profile with a reference. The system has an exclusive optical design making it easy for you to adjust the intensity to get the optimum picture by just pushing and pulling the attenuating filter adjustment levers. The beam profile can also be shown in a three-dimensional form which can be rotated to different angles and elevations.
Temporal Pulse Shape
The temporal profile of laser pulses, important in obtaining consistent process results, can now be easily monitored. Shown to the right is the pulse shape of the same pulsed Nd:YAG laser with 2ms pulses. It is being measured with a PC oscilloscope available as an accessory. You can display the pulse shape alone or together with the beam profile on your PC. Plug the Beam Cube output into an oscilloscope to observe the temporal pulse shape of your laser beam.
Average Laser Power
With the Ophir USB Interface between the Beam Cube unit and your PC or laptop, you can measure the average power of your laser to an accuracy of ± 3%.
Energy per Pulse and Frequency
Energy sensor inside the Beam Cube is able to measure the energy per pulse and the frequency of the laser to high accuracy. With the USB Interface you can display this on your PC or laptop screen.
Statistics
The Beam Cube with USB Interface is able to record and store an unlimited number of points in your PC. The software provided has a number of ways of displaying the statistics of the data.

Notes: (a) The power density limitation applies to any surface that the beam hits. For Beam Cube, since the object plane is outside the instrument, focal spots of much higher power density can be imaged as long as the power density limit on the optical surfaces is not exceeded.
Notes: (b) The Beam Cube will not resolve pulses of energy below 20mJ unless the pulse rate is high. If the energy deposited in 1/50th of a second exceeds 20mJ, then the unit will be able to show the pulses even though the individual energies are below 20mJ.
Notes: (c) If the beam power or energy density on the entrance window exceeds specifications, the window can be removed and not used, assuming that the power and energy density on the first beam splitter is below the damage threshold.
