چکیده
Изготовлены оптимизированные фотопреобразователи на основе гетероструктур GaInP/GaAs, выращенных методом металлоорганической газофазной эпитаксии, для работы с лазерным излучением высокой мощности зелено-красного спектрального диапазона. Для формирования лицевой контактной сетки приборов исследованы контактные системы Au(Ge)/Ni/Au и Pd/Ge/Au. В результате фотопреобразователь лазерной линии длиной волны 600 nm Pd/Ge/Au-контактом демонстрировал КПД более 50% вплоть до плотности падающего излучения 30 W/cm 2 максимальным значением 54.4% при 7 . Ключевые слова: фотопреобразователь, лазерное излучение, металлоорганическая газофазная эпитаксия (МОСГФЭ), КПД, спектральная чувствительность.

CNN-Gd(3+) enables cell nucleus molecular imaging of prostate cancer cells: the last 600 nm.
Molecular imaging is defined as the characterization and measurement of biological processes at the cellular and molecular level. Molecular imaging, therefore, necessitates a sufficient amount of contrast agent within the cell. Consequently, we realized that the intracellular uptake and cell compartment specificity of the commonly used interstitial contrast agent gadolinium (Gd(3+)) with a cell...
متن کاملHistopathological analysis of UV-B irradiated retina by Cavia Coba'ya and with protection of transmission light lambda 550-600 nm.
In 14 experimental Cavia Coba'ya eyes were irradiated with UV-B light, lambda 312 nm, 25 J/cm2 in 15 minute exposure. Including the transmission of light through optical media: cornea, lens, humor aqueous and vitreous body, and pupil surface of 7 mm2, we can calculate that in these conditions retina can be really irradiated with 10 J/cm2. The half number of Cavia Coba'ya was simultaneously irra...
متن کاملIn Vivo, Non-Invasive Characterization of Human Bone by Hybrid Broadband (600-1200 nm) Diffuse Optical and Correlation Spectroscopies
Non-invasive in vivo diffuse optical characterization of human bone opens a new possibility of diagnosing bone related pathologies. We present an in vivo characterization performed on seventeen healthy subjects at six different superficial bone locations: radius distal, radius proximal, ulna distal, ulna proximal, trochanter and calcaneus. A tailored diffuse optical protocol for high penetratio...
متن کاملAlignment control of GEO 600
Abstract We give an overview of the automatic mirror alignment system of the gravitational wave detector GEO 600. In order to achieve the required sensitivity of the Michelson interferometer, the axes of interfering beams have to be superimposed with a residual angle of the order 10−8 rad. The beam spots have to be centred on the mirrors to minimize coupling of alignment noise into longitudinal...
متن کاملThe status of GEO 600
The GEO 600 gravitational wave detector located near Hannover in Germany is part of an international network of gravitational wave observatories. As more and more of these detectors approach their final configuration, the focus is shifted from commissioning to detector characterization. At the moment, GEO 600, the first detector using advanced technologies such as dual recycling, is preparing f...
