Note that because fluence and intensity on the surface of the component are critical parameters, the area of the laser spot is also critical. I know how to calculate energy fluence (W/cm^2) of a pulsed laser, but if I shift the laser beam at a certain speed (cm/s) along a route I guess energy fluence will decrese. A Gaussian pulse shape is assumed. (b) Additionally, the phase-change from sp 3 to sp 2 from a pulsed ns-laser needs to occur within nanoseconds. The laser fluence was varied by changing the pulse energy. tunable laser where the bandwidth is < 1 nm. Unit converters and calculators of optical system and material properties (refractive index, dispersion), diffraction angles, laser pulse elongation, etc. Figure 19.12 shows two plots describing the feature depth machined against the natural log of the laser fluence required. The formulas used for laser safety calculations include numerous variables. For a low-gain laser amplifier, saturation fluence and energy can be calculated according to where h ν is the photon energy at the signal wavelength, σem and σabs are the emission and absorption cross sections at the emission wavelength, and A is the mode area . The area of each ablation-generated crater was measured using an optical profiler (Zygo NewView 600). Thereby, we can analyse simultaneously the influence of the beam-diameter and of the laser fluence on the ablation rate. However, safety calculations use the 1/e diameter, so check which one you are using for consistency in your calculations. 09 October 2019 5 1K Report. Assume all the pump energy is stored in the amplifier, but saturation effects will occur.

Thanks for the inputs! laser energy due to the air break-down in front of the sample. Holo/Or Ltd. develops, designs and manufactures diffractive optical elements (DOEs) and micro-optical elements since 1989. Our results show that by increasing the laser fluence, temperatures rise drastically both in the epidermis and dermis, although the phenomenon is more prominent in the epidermis. For a Gaussian circular beam, the peak fluence is the total pulse energy divided by πω2/2, where ω is the Gaussian beam radius. This calculator is designed for modelocked lasers with < ns pulse duration, between 315-1400 nm wavelength. Most laser beams have a Gaussian beam profile, so irradiance and fluence are both highest on the optical axis of the laser and decrease as deviation from the axis increases. Even if these are reflections from Most experts consider laser removal to be the most successful and cost-effective way to remove tattoos.

The whole fluence is determined by using the optic properties of each layer. Even very high-power lasers may be transmitted through or reflected off of a durable optical filter if the spot size is sufficiently large to reduce the fluence and/or intensity. When the laser pulse hits the material surface, part of the energy is lost by reflection. It is often necessary to calculate the power density (Power/Area) of a laser beam (for example, when trying to determine whether a beam will damage an optic or detector). Even very high-power lasers may be transmitted through or reflected off of a durable optical filter if the spot size is sufficiently large to reduce the fluence and/or intensity.

I have a question on how peak fluence is calculated. Specifically in optics, the fluence F e.g. CW or pulsed laser: Pulse Energy (Joules) = Average Power (Watts) * Pulse Duration (Seconds) Again, let’s use some real values and assume you are working with a CW laser that outputs 500 W. If you fire this laser at an object for exactly 5 seconds, then you have 500 W * 5 s = 2500 J. Often times, this system will need to be used with beam attenuation or beam sizing accessories, depending on your laser application. Enter the laser’s power in milliwatts. If you know the power in watts, multiply the watts by 1000 to get milliwatts. For example, for a 1 watt laser, enter 1000; for a 1.5 watt laser, enter 1500; for a 40 watt laser enter 40000. To calculate fluence use following formula: For Gaussian beams effective focal spot area it is determined at I0/e level of maximal intensity by CCDs and converted into the units of square centimeters. The peak intensity and fluence of the laser is given by Intensity (Watts/cm^2) = peak power (W) / focal spot area (cm^2) Fluence (Joules/cm^2) = laser pulse energy (J) / focal spot area (cm^2) while the peak power is Peak power (W) = pulse energy (J) / pulse duration (sec) There are several key parameters to consider for laser ablation. 4.3.1 Effect of laser fluence and number of shots.
