Now, we're trying to finda mechanically sound way to rotate the laser beam or prisms. However,after spending an hour trying to get these prisms to work at the biglaser, we realized that the beam's poalrization was not at 45 degrees tothe prisms and that's why we were unsuccessful. Aftertesting every single quarter-wave plate in the lab, we stumbled upon usingprisms instead (as Dr.Noe explained Khristine Horvat had done). Yiwei and I have been tryingto find an appropriate method to circularly polarize the laser beam. Of course, the former isunexpected while the latter was expected. This is similar to what happened when Itried to convert higher-order pseudo HGs. However, when experimenting withhigher-order plates, it creates several first-order singularities thatdon't converge into one dark core. The beam convergesinto what seems to be a HG and then into a vortex and into another HGthat's orthogonal to the first one. What's interesting to note is thatthese plates work very similarly to mode converters. Using Nityan's spiral zone plate, I wasable to get nice order-1 vortices.

It was rather ugly and required significant Maple work.Recently, I've been messing around with the idea of the circularlypolarized optical vortex tweezers. Infinity Blade 2 Cracked App Download High QualityĪbout two weeks ago, I completed the calculations for Marty's question,proving that tilted lenses or mirrors can't in fact create a perfect modeconverter.
