NettetLaser Parameters. Diameter (mm) Max Power. Calculate. Notes: Tophat calculations are for ideal tophat laser beams. For beams that are not 100% uniform, the peak power/energy density will be higher. Gaussian beam intensity is calculated for the 1/e^2 (13.5% of peak) beam diameter. #. NettetThe term “linear energy transfer (LET)” is used to indicate the average amount of energy that is lost per unit path-length as a charged particle travels through a given material. The LET for electrons is traditionally expressed in units of MeV/cm, or, when divided by the mass density, in units of MeV-cm2 /g.

"NettetLastly, two blocks (20 x 20 x 7 mm) with a rotation of the hatch area were built. This rotation was made in order to create a variable offset between -0.1 and 0.2 mm between the contour and the hatch area (core), as shown in Fig. 1(b). For simplicity, the linear energy density (EL) term was sometimes used for determining a P and v combination. " - Linear power density

In physics, the signal might be a wave, such as an electromagnetic wave, an acoustic wave, or the vibration of a mechanism. The power spectral density (PSD) of the signal describes the power present in the signal as a function of frequency, per unit frequency. Power spectral density is commonly expressed in watts per hertz (W/Hz). When a signal is defined in terms only of a voltage, for instance, there is no unique power assoc… NettetPower Density: Power per unit area, also known as irradiance.
