Hi You can get the Energy J by dividing Avg. Sensor Finder Laser Peak Power Calculator Laser Focal Spot Size Calculator Laser. To use this online calculator for Power density of laser beam enter Laser Energy Output P Focal length of lens f Beam divergence α Duration of laser beam ΔT and hit the.

Note that for a flat-top beam the equations are used just as is but for a Gaussian beam there is a factor 2 that multiplies the right hand part of these equations. The modeled laser pulses top and CW. Dividing the expression of power density of.

ED P v h t. We can write an expression for the power density of a1 mmdiameter beam which is simply. The acceleration of ions using modern high-power laser systems has led to the development of intense ion sources with high kinetic energy 123456Laser-driven ions with.

You can then use Energy and Power to calculate Energy Density Energy JArea cm2 and Power. We can write an expression for the power density of a1 mmdiameter beam which is simply. Of course a pulsed laser could damage a surface by the accumulation of total energy over time but that.

Power W of your Laser with its repetition rate. 1A 127 cm-2 1 mm diameter beam To get the. At 1e² it represents approximately 865 of the total power.

Laser-Induced Damage Threshold LIDT is frequently expressed in units of laser. That is the relative density first increased and then decreased as raising the laser. Laser power controlling the power density and cutting speed controlling the interaction time are the dominant factors influencing the quality in laser cutting of FRPs.

Where ED is the energy density or energy input ED in Jmm3 P is the effective laser power W v is the laser scan speed mms h is the hatch distance mm. The average power output by the pulsed laser. Average power provides no information about peak power period or pulse width.

Here is how this equation is derived. For pulsed laser beams you can enter the power or energy level to get the power or energy density of the laser. Laser Peak Fluence Intensity and Peak Power.

The laser power density is also a value that would affect how a material reacts to it. The laser energy density greatly affected the relative density of the SLM Cu-255Zn-4Al-06Mn SMAs. Laser Peak Fluence Intensity and Peak Power - LIDARIS.

To derive this formula we start with the easily verifiable fact that the reciprocal of the area of a 1 mm diameter beam is 127 cm-2. Use this calculator to determine the power density andor fluence energy density of your laser beam. And you will get your laser power density in Wcm 2.
