1. I know that the spot size of the laser tube increases with wattage and that a 40 watt tube spot size will engrave better than a 100 watt tube. I know that a 100 watt tube will cut thicker materials cleaner and faster.My first intentions of use will be mainly cutting and engraving on 3/4"(19mm) pine but I would like to also engrave and cut on other materials too. So my first question is how much less is the quality of engraving on a 100-130 watt machine versus a 40-60 watt model? Could a high resolution lens on a 100-130 watt machine engrave as fine as a standard lens on a 40-60 watt model?

The most important criterion when selecting the laser power of your laser machine is the application that you want to use most often with the laser. If the laser is primarily used for engraving, you will achieve good results with laser powers between 25 and 80 watts. For laser cutting or for very high speed applications, we recommend a laser power of more than 80 watts. Depending on the type of material, a different laser power will lead to the optimum result. E.g. Engraving paper usually requires less power than engraving wood. With acrylic, a uniformly homogeneous, not too deep engraving can be created using a low power. And when processing engraving materials (plastic laminates such as TroLase), higher power allows faster work.The laser power can be easily regulated by the software. However, the maximum power depends on the hardware. The following applies: A laser machine with high laser power offers great flexibility as it allows you to process many different materials.
