Laser Mechanisms is proud to introduce Tippy Gasjet as their official ambassador of laser beamdelivery information. Tippy provides helpful tips and explanations that are meant to offer a better understanding of the complex concepts surrounding laser beam delivery.Look for Tippy throughout The Laser Mechanisms Catalog and Sourcebook of Laser BeamDelivery providing a wealth of useful information. >

Abeam delivery system is what turns a laser into a functional tool. Except in extre-mely rare instances, a laser by itself is a useless device without a means to transport the beam to a workpiece and to transform, condition, manipulate, shape and focus it along the way.Beam delivery systems can be thought of as being either mirror-based ( conventional beam delivery )or fiber-based ( fiber-optic beam delivery or FOBD). Fiber-optic beam delivery is not presently pos-sible with CO transmission , reflectivity and absorption .The chart below shows where the wavelengths for various types of...

Most phenomena in physics are described as either being particle-based or wave-based.Light is unique in that it exhibits both particle behavior (transmission, reflectivity, absorp-tion) and wave behavior (polarization, mode, diffraction). Fairly early in the history of laser cutting a phenomenon was discovered whereby the cutting rate wasslower and the the cut kerf width was wider in one direction than in an opposing direction. This became understood to be attributable to the factor of polarization , or the direction of the energy inher-ent in a laser beam. Fortunately, once understood,...

Beam divergence is the measurement of the increase in beam diameter over distance,usually expressed in milliradians (take care to note whether the specification is half angle or full angle both expressions are commonly used). Although lasers characteristically have low diver-gence, in certain applications it is critical to collimate the beam (that is to make the light rays parallel)and reduce or eliminate divergence. This is particularly important when the beam is used at long dis- tances from the laser; when the beam path length changes as in a flying optic system and when the beam exits a...

ҕThere are both theoretical limits and (more realistically) practical limits as tohow small a beam of light can be focused. The first limit is that the beam cannot be focused smaller than the wavelength (example: 10.6 microns for CO > 2 and 1.06 microns forNd:YAG). The next limit (which makes the above purely academic) is diffraction .Diffraction is an inescapable, natural result of the wave nature of light, which causes energy tospread transversely (across the beam) as the beam propagates (similar to lightՒs particle nature of divergence). Diffraction is proportional to wavelength (so once...

Quite often in the world of laser processing, the answer to any question begins withthe qualifier, That depends onӅ Although at first this typical response may seem frustrat-ing, the truth is that a successful laser application is interdependent on a variety of factors.Once the basic principles are well understood, they are not that difficult to utilize into extremely pro-ductive results. Over the years, many users have developed reliable, repeatable laser processes, and many of these para- meters are now well known and shared in the applications community. Manufacturers of lasers and...
