…misalignments.
Applying HALT to entire laser assemblies is arguably even
more important and insightful as a development tool in guiding the design process. With a new laser design, such as with
an ultrafast oscillator, HALT puts a laser through increasingly
high levels of thermal…

processing is compatible with the preparation of large surface areas, can be readily automated, and delivers highly consistent results because it is a wear-free and
contact-free process. Plus, laser surface
preparation is applicable to…

…interference creates stationary, alternating zones of high and low laser intensity whose spacing is either equal
to the phase-mask period or half of this
value, depending upon the exact exposure geometry.
While this process is conceptually
straightforward, in the real world there…
