…focus over which the line thickness increases by 2. There are two distinct DOF conditions for the Coherent lasers. This comes from either focusing the slow or fast axis of the laser diode. Using the fact that these two axes have different divergences, we can select which one to provide the user for…

…Unlike incoherent sources, coherent laser sources behave in a manner that even under ordinary circumstances is relatively easy to describe. The nature of the laser cavity design, in common laser diodes, dictates the beam properties. The beam being emitted from the diode begins as a plane wave with a…
