Real-Time Divergence Measurement
By monitoring the divergence angle θ, it is possible to make a measurement that will be directly proportional to M2. This enables the adjustment of the laser performance in real time at the NanoScan’s rapid update rate (up to 20Hz). To use this feature, the scan head is moved to a position one geometric focal length from the test lens. Divergence is the beam diameter divided by the focal length, and the measured divergence is equal to M times the embedded divergence.
Therefore when the beam diameter at this location is minimized, the divergence is at its minimum and the M2 of the laser should then be optimized. After this real-time adjustment, the full M2 measurement can be done to generate the required parameter values. This method makes the NanoModeScan an even more valuable tool for the final setup of lasers on the manufacturing floor by decreasing the time it takes both to adjust the laser system and to make the measurements required for quality control documentation.

If you are an industrial laser user, you are well aware with the concept that time is money. And when it comes to maintenance on your laser, this principle certainly applies. However, you also know that maintaining your laser is a must if you want to ensure that your process is as efficient and consistent as possible.
Ophir-Spiricon’s BeamCube product is about as a simple a product as they come. It is a device that has integrated laser power or singlepulse energy measurement, focused spot analysis, and temporal pulse shape measurement all within one black box. The user of a BeamCube can measure the focused spot down to 60 µm, average power up to 150W or 100J per pulse, and pulse widths as short as nanoseconds in duration.
Spatial Beam Profile
BeamCube comes with BeamGage-Standard, the most popular laser beam profiling software on the market. Accurate measurements of the beams size, shape, uniformity or approximation to the expected power distribution, as well as its divergence and mode content can easily and quickly be made and stored for future reference.

Average Laser Power
With the built-in thermal power sensor you can measure, collect and store average power measurements within +/-3%, NIST traceable.
Temporal Pulse Shape
The temporal profile of laser pulses, important in obtaining consistent process results can also be measured using the built-in PC oscilloscope. You can display the pulse shape alone or together with the beam profile on your PC.
Store and Compare Data and Statistics
Important for consistent laser process verification, measurements and statistics can be stored and later retrieved for comparison to subsequent laser performance.

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.

3.8 High-Power Applications
3.8.1 High-Power NanoScan
Photon’s High-Power NanoScan can measure focused CO2 laser beams up to 5 kilowatts. The High-Power NanoScan is equipped with a pyroelectric detector with copper slits and drum. A cooling fan mounted on the scan head body provides additional heat management. With the new “peak connect” algorithm and the software controlled variable scan speed, the High-Power NanoScan is ideal for measuring lasers operating with pulse width modulation (PWM) power control. Measurement of Q-switched lasers and other higher frequency pulsed lasers is also possible using this feature.
What Can be Measured?
Measuring high-power beams can be tricky. The lasers have the potential to damage the scan head, and any reflected light can be dangerous to both the operator and the surroundings. The High-Power NanoScan can measure these beams because it uses a
combination of highly reflective components with high thermal dissipation capability. It is important to manage the reflected beam so that it neither reenters the laser cavity nor sends stray beams into the surrounding area. The scan head is designed to make short duration measurements to avoid excessive heating of components. The head should be only in the incident beam for 10 to 60 seconds depending on the power levels to prevent excessive heating of the components. The High-Power NanoScan scan head has been shown to be able to handle power densities of 3.2MWcm-2 at 10.6µm, the power density of a 200µm beam at 1kW. At the shorter wavelengths of the other common industrial lasers, Nd:YAG and DPSS, the upper limits are a little less, due to the slightly lower reflectivity of the components at wavelengths around 1000nm. Visible and UV lasers can also be measured, but these will have lower limits yet.
The chart below shows the damage thresholds for pulsed beam energies for the three wavelength regimes. The lines represent the maximum energies per pulse for various spot sizes that correspond to 5J/cm2 for the 3µm to 100µm wavelengths, 2.5J/cm2 for the 700nm to 3µm range, and 250mJ/cm2 for the UV-Visible range from 190nm to 700nm. When operating with pulsed lasers, calculate the energy per pulse to ensure that the values fall below these lines for the wavelength of the laser. Operation above these values will likely cause damage to the scan head apertures.

3.8.3High Power - ModeCheck® - A New Method to Assure the Performance of High Power CO2 Lasers
ֺ |
Beam Profiler for collimated 50W-5KW, 10.6um wavelength, beam width up to 30mm. |
Laser Beam In |
ֺ |
Quality Cutting, Marking, Drilling & Ablating Require More Than Consistent Laser Power |
|
ֺ |
Instantaneously “see” and measure the beam - reduce set-up time between jobs |
|
ֺ |
Real-time “mode burns” - eliminate hazardous acrylic vapors |
|
ֺ |
Optimize laser efficiency - reduce cost per part |
|
ֺ |
Predict laser preventative maintenance - increase manufacturing efficiency |
|
ModeCheck is designed for the industrial parts manufacturer to reduce the time it takes to change over between different jobs. The user can quickly place the ModeCheck in front of the laser and see and measure, in real-time, the laser beam profile to confirm optimal laser performance. In addition, and when used periodically, the user can compare measurement changes from the same set-up and make necessary laser adjustments, keeping the laser output constant for the same job from day-to-day. Over time the user will be able to see and measure laser degradation to predict and advance schedule down-time needed for periodic maintenance.
Pass-Through
Beam Out
ModeCheck eliminates operator exposure to acrylic mode burn hazards while improving product quality and manufacturing efficiency.
Measurements:
In addition to both 2D and 3D graphical image display and save, the following measurements are made from each image:
ֺBeam Widths and Diameters
ֺBeam Position Stability
ֺPower Density Peak
ֺBeam Centroid Location
ֺElliptical Analysis with Major Axis Orientation
It’s just this easy.
1.Remove Focusing optic
2.Locate the beam center with pointing beam or similar device
3.Place ModeCheck in beam center
4.Turn on Laser
5.Instantly see, measure and electronically store the beam characteristics
Optional Accessories
One must manage the pass-through laser beam by collecting the beam using either a power meter or beam dump. We recommend using a power meter as the additional measurement information will assist in managing laser optimization. Note that any beam dump or power meter large enough to handle 5kW will require water cooling. There are holes on the bottom of ModeCheck for mounting the Power Meter Head or Beam Dump.
A ruggedized storage/carrying case is highly recommended for safe and efficient handling.
The ModeCheck Lens Adapter (MLA) is an option that will enable a ModeCheck to recollimate a focused CO2 laser beam. The advantage of using this adapter is that the focusing head of the machine does not have to be removed, which is the normal case for a ModeCheck without this adapter. The disadvantage is that the ModeCheck must be positioned further from the output head in order to properly recreate the collimated beam profile. The re-
collimating lens must be supplied by the user and must be the same lens that is used on the lasers cutting head. (See application note: SP90329).
A PC is required to run the ModeCheck imaging software. The camera is powered over the USB cable that connects the computer to ModeCheck.
ModeCheck makes instantaneous beam measurements along with graphically displaying both the 2D and 3D power density distribution
