The discovery of Rayleigh Scattering by 3rd Baron Rayleigh, John William Strutt, served an explanation of why the sky is blue during the daytime and different hues of orange, pink, and purple in the early morning hours and at dusk. But it was only recently that this phenomenon has been applied to the measurement of high-powered lasers. Only through the measurement of the laser source and laser system can the user of the laser fully understand its performance and then start to control the processes in which they are used. Key laser parameters which ensure a successful process include output power or energy at the work piece, spot size or beam waist size, spot size location (over time), in addition to M2 or Beam Parameter Product values. Since the beginning of the application of the high-powered laser, and with recent steady increases in continuous-wave power, measurement has proved to be more and more problematic. This paper will discuss how the signal of the laser produced from Rayleigh Scattering can put to rest any concerns by the laser user of damaging their laser measurement equipment. The high-power laser user can now obtain dynamic characteristic measurements, instantly from beam
