Laser sets a new state of the art on zero-shot cross-lingual natural language inference accuracy for 13 of the 14 languages in the xnli corpus. it also delivers strong results in cross-lingual document classification (mldoc corpus).. General natural organic materials laser system considerations. platform size – must be large enough to hold the largest pieces of natural organic material that will be laser processed or be equipped with class 4 capability for processing larger pieces. wavelength – the 10.6 micron wavelength is absorbed well by all organic materials and is the best choice for laser cutting, engraving, and. Laser engraving of stone is a type of stone processing with the help of a focused laser beam, through which an image is formed on the stone (drawing, text, pattern, portrait). endurance made a few tests and found out that it is possible to engrave on a natural stone surface with a single pass at an average speed of 100-250..
Laser power – must be selected based on the processes that will be performed. 25 to 150 watts (co 2 laser) is best for laser marking natural inorganic materials. higher laser power should be used for laser cutting and engraving. lens – a 2.0 lens is the best general process lens for natural inorganic laser material processing.. For example, laser‐induced ablation of graphite, discovered in the 1990s, is commonly used for the targeted synthesis of cnms. [7, 8] high‐power laser pulses hit a graphite target and create a carbon plasma above the surface, which reacts to crystalline nanocarbons. these laser‐assisted synthesis methods differ from conventional thermal.
