spikelab.mycpanel.princeton.edu4.2 Fundamentals of Laser Surface Processing One of the major advantages of the laser as a tool for material processing is the abil-ity to precisely control where in the material and at what rate energy is deposited. This control is exercised throughthe properselection of laser processing parameters to achieve the desired material modification.

Dynamic Light Scattering Training
www.chem.uci.eduthe laser wavelength (› For the He-Ne laser ( = 633nm) used in the Zetasizer, this equates to particles less than about 60nm › The scattering produced by such small particles is isotropic i.e. equal in all directions › The intensity of light they produce is proportional to d6 where d is the particle diameter (ie. I α 6d)
