We present the first multi-Watt demonstration of a diode pumped cryogenically cooled neodymium-doped yttrium aluminum garnet (YAG) laser operating at 946 nm on the (4)F(3/2) → (4)I(9/2) transition. 3.8 W of continuous wave output power for 12.8 W of absorbed pump was obtained with a slope efficiency of 47%. In addition, we made an extensive characterization of the spectroscopic properties aroun...

To discuss diagnostic strategies and management options in cases with suspected valsalva maculopathy (VM), to optimize visual outcome. We describe six cases with suspected VM. The preretinal hemorrhage resolved spontaneously in four out of six patients, without any intervention. One patient underwent neodymium-doped yttrium aluminum garnet hyaloidotomy and the other proceeded to have a vitrecto...

This work presents a novel white light device. An yttrium aluminum garnet (YAG) phosphor-incorporated zinc oxide (ZnO) film is deposited on a slide glass substrate by ultrasonic spray pyrolysis. A nanoflower consisting of a hexagonal nanopetal is formed on the surfaces of the samples, and the sizes of the nanopetal are approximately 200 to 700 nm. Additionally, the nanopetal becomes blunted wit...

Vascular air embolism (VAE) is a rare, but potentially fatal complication of invasive medical or surgical procedures. It is a very rare complication of bronchoscopy and is most frequently reported with therapeutic bronchoscopy with Argon plasma coagulation (APC) or neodymium-doped yttrium aluminum garnet (Nd-YAG) laser. Despite being rare, as a result of its high chance of mortality and morbidi...

A charge compensation mechanism is proposed for cation vacancy defects in complex oxides based on positron lifetime measurements, infrared spectroscopy, and composition analysis. Defects were characterized in samples of yttrium aluminum garnet grown in O2 or Ar. However, no positron trapping was detected in samples grown in H2. This is attributed to decoration of cation vacancies with hydrogen,...

Neurilemmomas are benign tumors which originate from Schwann cells. They rarely occur in the trachea or bronchus. We encountered two cases of endobronchial neurilemmoma and in this context, reviewed 48 cases previously reported in Japan. Neurilemmomas can occur in all regions of the bronchial tree and they often progress into both intraluminal and extraluminal spaces. Incomplete resection resul...
