Irradiance to fluence
Web4.3.1 Effect of laser fluence and number of shots. Different laser fluences were used to determine the energy range needed for gold melting in the case of rough substrates (Ra > 0.15 μm corresponding to gold thickness higher than 0.75 μm) commonly used in industry. For small fluences (lower than 400 mJ/cm 2 ), laser impacts were not observed. WebMay 20, 2024 · FIG. 3 – Spherical irradiance (fluence rate) For UVGI applications, we are interested in the ultraviolet dose, or fluence, of the droplet, measured in millijoules per square centimeter. Unfortunately, there are no practical instruments to accurately measure ultraviolet fluence, apart from spherical actinometers – hollow quartz spheres ...

Did you know?
WebIrradiance (or flux density) is a term of radiometry and is defined as the radiant flux received by some surface per unit area. In the SI system, it is specified in units of W/m 2 (watts per square meter). Irradiance may be applied to light or other kinds of radiation. Figure 1: Irradiance is received radiant flux per unit area. WebThe quick answer is that since an elliptical Gaussian beam is separable into a product of one dimensional Gaussian beams with axes oriented along the ellipse's major and minor axes, you just need...
