FAQ

What is the best beam width measurement method?

The answer depends on what information is wanted from the beam width.

  • The most representative measurement of a beam width in determining how the beam will propagate is the Second Moment measurement. However, the Second Moment measurement can have problems if there is diffraction in the beam before measurement, which puts a significant amount of energy in the wings. This energy may diverge faster than the rest of the beam, and if it is included in the measurement, it will give a beam width much wider than reality. However, an aperture can be used to limit the beam width measurement to energy inside these diffraction rings.
     
  • A second very good measurement of beam width is the software equivalent knife-edge measurement. This measurement is less sensitive to diffraction in the wings of the beam, although it will give a beam width measurement which is weighted by energy out in the wings. It is less sensitive to noise.
     
  • Sometimes the most important information is not the beam propagation characteristics, but how much energy is near the peak of the beam. In this case, a percent of peak beam width measurement would be more useful.

The calibration date on my M2 system has expired. What do I need to do to get it re-calibrated?

After numerous requests for re-calibration of M2 systems, in 2008 Ophir-Spiricon started a recalibration program for its M2 systems. This program allows the equipment to be sent back to the factory to be inspected, lubricated and re-calibrated. This enables customers to comply with their ISO regulations. Please click the below link to be directed to a section of our web site where you can request an RMA to return your equipment for re-calibration.

It has been suggested that if the M² results are computed to be < 1 we should display a 1 as the answer. However the algorithms in the M²-200/200s software make computations and report results as the input settings and the beam samples dictate. This is done so as to provide useful information to the operator rather than to try and conceal something. There are two common occurrences when M² results are less than 1.

The first and most common of these have to do with the operator entering the wrong wavelength value. In this case the results are often well below 1, in the .8-.9 range. The second most common cause for results <1 is due to nominal accuracy tolerances. These are normal and expected. With a 5% M² tolerance results from ~.95 to ~1.05 are very possible. Averaging runs will normally return a mean value to something > than 1, but not always.

BeamWatch™ utilizes disruptive technology to measure very high power YAG and fiber lasers. By not intercepting the beam and yet providing instantaneous measurements, you can now monitor the beam characteristic at frequent intervals without having to shut down the process or remove tooling and fixtures to get access. In addition, you can now measure focal spot location at millisecond intervals and know if there is any focal spot shift during those critical start-up moments.

Attenuation-Induced Error Due to Thermal Lensing in Beam Measurement

The need to profile lasers with powers in the 10mW to 1W range are becoming more common. Many of these lasers are in the visible spectrum, allowing them to be measured with CCD and CMOS camera systems. As with any laser that is being measured with a camera array, the beam needs to be attenuated, but there are some cautions to be observed. These beams are not so powerful that they will damage or destroy typical absorptive filters. In fact, it is possible to stack up a sufficient optical density to reduce the power of a 1W laser to the nW levels that will not saturate the detector. Read more...
