Polygon scanners can move a laser beam > 10x faster than a galvanometer scanner. The simplest implementation of a polygon scanner is a very fast line scan across a moving target. In applications like laser cleaning or surface treatment, a…
High power 1064 nm lasers have become very popular for material processing. 1064 nm is invisible to the human eye but it is still necessary to have some method to visualize the beam. Coated paper Laser Viewing/Detection Cards block 100%…

When galvanometer (galvo) scanners are not fast enough, a Polygon Scan Head may be the solution. A Polygon Scan Head can scan at hundreds of meters per second. Here is a block diagram of a single axis Polygon Scan Head. …
Beam shaping is well known in material processing. The normal Gaussian beam profile may be is converted to a top hat (flat top) to more efficiently utilize the full energy of the beam. The same beam shaping optics can also…
Many laser systems have a beam expander to change the diameter of the beam from the source to match the requirements of the optical system. Most beam expanders have two or three lenses to accomplish the task. While three lenses…
The Focal-piShaper 9_HP presents a new version of refractive focusing beam shapers optimized to operate with modern high power Ultra-Fast (picosecond & femtosecond) lasers. Optical design of the Focal-piShaper 9_HP is adapted to high pulse energy and provides reliable transformation…
Life in the Ultrafast Lane with Fiber Lasers describes the progress being made by the industry to increase power levels of Ultrafast lasers using fiber technology. The article illustrates the superiority of Ultrafast /Ultra Short Pulse (USP) lasers for clean…
It is common practice in low power polygon scanner systems to use the working beam to trigger a Start-Of-Scan (SOS) detector. The SOS trigger is essential for accurate laser scanning. Polygon Scan Heads, used for material processing, employ high power…
It is a fine achievement for Road Runner to push the top speed of polygon scanning to a record breaking 70,000 RPM and to solve the noise problem with a whisper quiet design! See and hear a Road Runner demonstration…
