Lasers are dynamic sources of energy which are ever changing. The laser is prepared for the application through a series of optics varying in quality and complexity. Fluctuations in the laser and the imperfections in the optical train will affect, to some degree of significance, the performance of the beam at the work site. Measuring these variables and their effects on the laser performance has been very inconsistent. Many measurement techniques are based on the perception of the person making the measurement. Inconsistencies in perception affect the results and performance quality of the system.
