Laser power density formula

Whether using the laser as a tool or ensuring its safety you dont. 1A 127 cm-2 1 mm diameter beam To get the power density of a 1 mm diameter beam one must simply multiply the power in Watts by 127 cm-2 to get power density in Wcm2.

Laser Control Measures General Concepts Environmental Health And Safety Oregon State University

Gaussian beam intensity is calculated for the 1e2 135 of peak beam diameter.

. 1 Laser energy density laser power laser spot size scan speed The eqn 1 shows that at high scan speed laser energy density is low and may not be sufficient to process the powder. Note that for a flat-top beam the formulas are used just as is but for a Gaussian beam there is a factor 2 that multiplies the. For beams that are not 100 uniform the peak powerenergy density will be higher.

Well use the formula for calculating power density of a practical antenna Power Density P D P out G tx 4 π D 2 Given that. P out 100W G tx. Laser-Induced Damage Threshold LIDT is frequently expressed in units of.

The power density is determined by the power of the laser divided by its cross-sectional area or beam size.

Dividing the expression of power density of a 1 mmbeam Power π05mm 2 by an expression of power density as a function of diameter Power π05d 2 we find.

The lasers power density at its aperture zero distance is mathdfracPA dfracPpi a b dfrac300 textmW14 pi mathrmmm2 approx 6821 mathrmW. The Power density of laser beam formula is defined as the power contained in per unit area of beam cross section and is represented as PD 4P pif2α2ΔT or Power Density of. Laser Peak Fluence Intensity and Peak Power - LIDARIS.

Laser Peak Fluence Intensity and Peak Power. I have also attached a file that. To be specific energy.

We provide peak power density threshold values for most laser power detectors thanks to a simple calculation relating energy density threshold to the former. Dividing the expression of power density of a 1 mmbeam Power π05mm 2 by an expression of power density as a function of diameter Power π05d 2 we find. At 1e² it represents approximately 865 of the total power.

LPD Laser Power Density Wcm 2 d Diameter of laser beam mm P Power of laser beam watts Enter the diameter and power of the laser beam and click calculate to find the laser. You can then use Energy and Power to calculate Energy Density Energy JAreacm2 and Power Density Power WAreacm2.
