We report on a patient who developed capsular block syndrome (CBS) in the early postoperative period with marked myopic shift in absence of anterior dislocation of the posterior-chamber intraocular lens (PC/IOL) and iris diaphragm. Treatment with focal 6-o'-clock Nd: YAG-capsulotomy resulted in complete visual acuity restoration. To the best of our knowledge this is the fist case of early onset...

We report on optical detection of a single photostable Ce(3+) ion in an yttrium aluminium garnet (YAG) crystal and on its magneto-optical properties at room temperature. The spin quantum state of the emitting level of a single cerium ion in YAG can be initialized by a circularly polarized laser pulse. Coherent precession of the electron spin is read out by observing temporal behavior of circula...

Single-crystal rare-earth doped YAG fiber lasers grown by the laser-heated pedestal growth technique Report Title High concentrations of the rare-earth elements erbium, holmium and thulium have been successfully doped into single crystal (SC) yttrium aluminum garnet (YAG, Y3Al5O12) fibers by use of the laser heated pedestal growth (LHPG) method. The spontaneous emission spectra and fluorescence...

Author comment (AC)1: SUP05 was indeed present in the dataset; we presented the diversity on the phylum level, SUP05 would only show up on the family level and clusters within the phylum of Proteobacteria, as shown in figure 4. In order to provide a deeper insight into the distribution of SUP05 and other organism groups, we now included a table and a bar plot including all taxa on the family le...

In this talk I present the results of an analysis of total and inelastic hadronic cross-sections for photon induced processes in the framework of an eikonalised minijet model(EMM). We fix the various input parameters to the EMM calculations by using the data on photoproduction cross-sections and then make predictions for σ(γγ → hadrons) using same values of the parameters. We then compare our p...

Исследованы нелинейно-оптические характеристики Cr4+:YAG кристалла методикой Zсканирования по схеме с открытой апертурой. В качестве пробного источника использовано излучение непрерывного лазера на длине волны 1030 нм мощностью до 400 мВт. При этом наблюдалось нелинейное поглощение лазерного излучения, которое связано снасыщением возбужденного состояния кристалла. Определена интенсивность насыщ...

One of the most common cause decrease vision in a pseudophakic patient is formation posterior capsular opacification (PCO) which affected by several factors like design implanted intraocular lens (IOL) and material IOL. PCO incidence has been reported to be 20.7% at 2 years & 28.5% 5 years. Decrease because necessitates capsulotomy with neodymium yttrium aluminum garnet (Nd-YAG) laser create sm...

CASE REPORT A 78-year-old man presented with a 2-week history of decreased vision in the right eye (RE). Ocular history included uncomplicated cataract surgery in the RE 2 years earlier. Gonioscopy revealed a retained small nuclear fragment (sNF) in the anterior chamber (AC) and OCT showed macular edema (ME). The NF was fragmented with a YAG laser. DISCUSSION AC retained NF resulted in ME and...

We present our recent advances in the use of pulsed laser deposition (PLD) to fabricate active gain elements for use as amplifiers and laser oscillators. Record output powers exceeding 16 W and slope efficiencies of 70% are reported for optimized epitaxial growth of Yb(7.5%):YAG on to YAG substrates. We show for the first time that the performance of PLD material can meet or even exceed that of...
