Today, DOME Fiber Closure suppliers share knowledge of fiber lasers Fiber optic lasers have an electro-optic conversion efficiency of more than 30%, while lamp-pumped YAG lasers are only 1.5% to 2%; no need to replace flash lamps, resulting in more cost savings: fiber-optic lasers use carrier-grade single-core junctions with a lifetime of up to 100,000 hours Semiconductor laser tubes; spot size and shape are fixed at all power levels; maintenance-free or maintenance-free operation; few spare parts; very small size; longer working distance; no adjustment required; no preheating required. How to adjust the fiber laser? The method is very simple. For fiber lasers, this is the process of imaging a fiber output on a workpiece. The spot size is equal to the fiber diameter multiplied by the magnification ratio of the collimating mirror and the final focusing lens diameter. For example, if the fiber diameter is equal to 50 μm, using a 60 mm collimating mirror and a 300 mm final focusing lens, the final spot size SS = 50 x 300 / 60 = 250 microns. The fiber diameter, collimating mirror, and final focusing lens can be adjusted to meet spot size requirements. The spot size does not vary with the dynamic range of 5% to 105% of the rated power. The single-mode laser spot size is a Gaussian beam spot and a low-order mode laser apex.
