    摘要： A system and method of laser etching materials is provided. A series of optical elements are used to reduce the spot size of a laser for a given field size, allowing fine detailed graphics associated with small spot sizes to be etched with larger field sizes. This may be accomplished, for example, by increasing the size of a laser beam beyond its natural state before passing the beam through a focusing lens, such expander lens, focus lens and mirror system increased in size so as to generate a laser spot size less than or equal to 0.5 mm at a field size equal to or larger than 1500 mm square.

    摘要： A layer of material is removed from a surface (14) of a bonded abrasive product (10) by directing a laser beam (18) at the surface (14), causing the laser beam (18) to traverse the surface to damage the surface (14) to a desired depth and removing the damaged material remaining on the surface (14), for example by lapping. The bonded abrasive product (10) is particularly a diamond compact.

    摘要： High powered lasers are used to score the bark (28) on logs (26) before they are mechanically debarked. Typical of the lasers employed are multi-kilowatt CO2 industrial lasers. A high powered laser beam (20) is brought to a focus just above the surface of the bark (28) on the log (26). A jet of compressed air is blown co-axially with the beam and facilitates the beam's formation of a narrow slot in the surface of the bark. Logs are advanced and rotated by a plurality of parallel augers (42) extending across the base of a trough (40). The lasers are positioned in a gap beneath and in between sets of augers. The beam's focus may be adjustable with respect to the bark's surface. The motion of the log with respect to a laser head produces a spiral cut along the surface of the log which slices the long fibers in the bark.
