Co2 Laser Beam Spot Size

Spot size is nothing but the radius of the beam itself.

Co2 laser beam spot size. From laser welding applications to wafer dicing or eye surgery knowing your beam divergence is a must for building a functional setup and to direct the energy precisely where it is needed for a. M means one special laser beam s divergence speed in transmission for one ideal laser beam m 1 laser source supplier will offer this parameter in their technical sheet. Calculator provides circular or elliptical spot size approximations based on 1 e 2 beam diameter and beam divergence. Focal spot size calculator for gaussian laser beams use this calculator to get the size and location of your gaussian laser beam waist at focus as well as the rayleigh range.

Laser beam spot size and depth of focus calculator. The irradiance of the beam decreases gradually at the edges. For a more extensive application file please check co2 laser applications in cutting. It is defined in milli radiant mrad which usually describes a part of the circumcircle.

Find the spot size and depth of focus for a given laser and lens configuration. They come with a variety of tips for different procedures all of which can be sterilized. For example if the sensor has a pixel pitch of 5 5 µm you should not try to measure beams smaller than 55 µm with it. For the pixel pitch or equivalently pixel size we recommend that the smallest beam you will measure should fit within at least 10 pixels.

Remember we calculated the power density intensity of a 50 watt laser at 0 4 mm spot size 400 micron was 400 w sq mm. Beam behavior over distance the beam divergence describes the widening of the beam over the distance. Each handpiece features zoom optics to focus and de focus the beam and adjust the spot size of the handpiece. Our accu beam variable spot size handpieces are a range of articulating arm co laser attachments for a variety of different procedures.

The distance across the center of the beam for which the irradiance intensity equals 1 e2 of the maximum irradiance 1 e2 0 135 is defined as the beam diameter. Laser beam quality m such as you saw in above formula spot size is direct ratio relationship with beam quality m. For lasers beam diameter is given for tem 00 mode. Input parameters are explained further by mousing over the information i icon.

Laser beam divergence is one important parameter to know for laser manufacturers and users alike who need to take control of their laser spot size.
