    Notes: The photorefractive properties of a poled polymer containing the tricyanovinylcarbazole group with an alkylene spacer are investigated by four-wave mixing experiments and Mach–Zehnder type electro-optic measurements. The photorefractive effect is demonstrated in a polymer that shows both the photoconductivity and the electro-optic effect intrinsically.

    Notes: A conventional 30-turn thin-film head does not yield sufficient output when applied to a small-size rigid disk drive, especially 3.5 in. or less. A head of higher output voltage with more turns is required to obtain larger signal-to-noise ratio. A 48-turn thin-film head with two-layered spiral coil has been successfully developed, and 1.6 times the output voltage and larger signal-to-noise ratio by about 3 dB compared with the conventional 30-turn head were obtained. The head has a 0.55-μm gap length, 17-μm track width, and 4-μm-thick Permalloy films on the 3370-type slider. Yoke length was designed to be the same as that of the 30-turn head to prevent the reduction of the head efficiency. To minimize the increase of the coil resistance due to increasing the coil turns, the copper coil was fabricated with a high-aspect-ratio process using oxygen-ion milling of photoresist. Coil width was 3 μm; coil pitch was 4.5 μm, and coil thickness was 4 μm. These heads were evaluated using a 3.5-in. sputtered disk and showed good electromagnetic performance.

    Notes: Multilayer reflectors and position sensitive detectors have been developed in constructing imaging optical systems in the 45–300 A(ring) region. Molybdenum-silicon (2d=140 A(ring), N=20) and nickel–carbon (2d=100 A(ring), N=20) multilayers were deposited on a spherical mirror (25 cm in diameter) for the normal incidence and on a segment of paraboloidal mirror (20 cm×10 cm) for 30° grazing incidence. Their optical characteristics were evaluated by using characteristic x rays and monochromatized synchrotron radiation in the 45–300 A(ring) region. A position sensitive detector is made of a tandem microchannel plate (MCP) with a CsI photocathode and resistive plate, which is placed at the focal plane of each mirror. The detection efficiency and position resolution were measured by using characteristic x rays of CKα and monochromatized synchrotron radiation in the 45–200 A(ring) region.

    Notes: The method of XAFS measurements at high temperatures and pressures for supercritical fluids with high critical constants have been developed. An internally heated high-pressure vessel made of super-high-tension steel and a polycrystalline sapphire cell of our own design permit XAFS measurement up to 800 bar. XAFS experiments were carried out at high temperatures up to 1600 °C, and high pressures up to 150 bar. XAFS spectra of liquid Se at 1300 °C and 150 bar, and dense Se vapor at 1600 °C and 150 bar have been obtained and clear oscillations are observed at these temperatures. © 1995 American Institute of Physics.

    Notes: Small-signal transient absorption of a discharge-pumped F2 laser (157.6 nm) medium was measured by using a Raman-shifted F2 laser (168.6 nm). The small-signal total absorption was obtained for 6 atm laser media at an excitation rate of ∼26 MW/cm3, where a small-signal net gain was independently measured to ∼35%/cm, as the sum of a transient absorption of ∼2.5%/cm and a stationary absorption of ∼0.5%/cm. In spite of the relatively large gain-to-loss ratio a significantly low maximum laser intensity of ∼2 MW/cm2, which gives zero extraction efficiency in the F2 laser medium, measured in heavily saturated F2 laser amplification experiments, suggests that the energy extraction is limited by additional absorption.

    Notes: Today, it is said that the formula design of cosmetics from ingredients of plant origin is an indispensable way and trend. From this consideration, cosmetic materials made from animal and synthetic petroleum ingredients are becoming less usable. Instead, cosmetic materials are designed from ingredients of plant origin and many and various botanical ingredients are being developed. Lanolin, which is one of the animal-based ingredients, is said to have ideal functions as a cosmetic oil, and it has been used in many fields such as make-up cosmetics as well as hair and skin care products for a long time. However, unfortunately, lanolin is an animal-based ingredient; therefore, the development of a botanical ingredient to replace lanolin was desired. Polyglyceryl-8 decaerucate/isostearate/ricinoleate, which we have developed, is an ester oil originating from plants and has an equivalent or higher function than lanolin. We have confirmed that our developed ester oil has various excellent characteristics such as a water-holding capability 2.5 times higher than that of lanolin, high air permeability, moisture keeping in dermal layers, protection of hair from changes in external environmental humidity, and excellent gloss and excellent dispersability of pigments. Thus, this newly developed ester oil is expected to be a promising new botanical cosmetic ingredient which can be applied in various fields.

    Notes: We report on the synthesis and characterization of a new, completely polymeric material with a large electro-optic coefficient and photoconductivity. A methacrylic ester polymer containing the tricyanovinylcarbazole group with an alkylene spacer was synthesized. With 49 mW laser power, the photoconductivity of the polymer is 9.8×10−10 Ω−1 cm−1 at an applied electric field of 1.4×106 V/cm. Its electro-optic coefficient is 6.1 pm/V. The quantum efficiency of photocarrier generation and the photorefractive figure of merit were calculated. This electro-optic polymer is photoconductive and has photocarrier trap sites without any added sensitizer or photocarrier transport reagent, making it a suitable candidate for photorefractive applications.

    Notes: To date most passively mode-locked erbium-doped fiber laser systems have employed solitons for short pulse generation, and ultrashort high energy pulses have been difficult to achieve. We show that by reducing the system nonlinearity via pulse stretching and employing net positive dispersion cavities, pulses of sub-100-fs duration and (approximately-greater-than)100 pJ energy are readily generated. Data are presented for varying net dispersion in a fiber ring.

    Notes: Stretched-pulse additive pulse mode-locked fiber lasers use fibers with opposite signs of group velocity dispersion to introduce large changes of pulse width per pass and avoid excessive nonlinearity. We have investigated these intracavity pulse dynamics. Optimal points for output coupling and for the placement of the artificial absorber element in the cavity are determined for a fiber ring laser. The dispersion balance is important for the generation of clean sub-100 fs pulses, but the net cavity length is found to be relatively uncritical. © 1995 American Institute of Physics.
