…Plastics Diode lasers, with wavelengths in the range of 808 nm to 980 nm, are typically used to join various plastic material combinations in plastics welding applications. Diode lasers are used to weld plastics, applicable for thermoplastic materials only. In one welding geometry example, the laser…

…to burn damage and optical losses. Assembling these lasers in a tightly controlled clean room setting was a first mandatorystepbutfailedtoconsistently address this problem, especially with very short pulse lasers (i.e. < 20-40 fs). At Coherent, we solved this problem by adapting methods used in our…

…play a part in the speed and accuracy of beam-characterization systems. There are many ways to obtain one or more parameters of a laser beam. One venerable approach, specific to high-power carbon dioxide (CO 2 ) lasers, is called a mode burn, in which an acrylic block is placed in the path of the…

from burned materials; results do not reveal short-term fluctuations. Last but not least, the human eye features a
logarithmic sensitivity; it can only see a limited number of shades; and it has difficulty to distinguish enough structure
in burn spots.
