Since the first experimental demonstration of Bose-Einstein condensation (BEC) in an alkali-metal vapor, this subject has been attracting remarkable interests in the physics society. Hundreds of theoretical works concerning this subject have been reported so far. However, the number of reports about BEC experiments is much less than that of the theoretical works. This is because only a few experimental groups have succeeded in realizing BEC due to the experimental complexity and difficulties. The first step to create BEC in alkali-metal vapor is to collect a large number of atoms (/spl sim/-10/sup 9/) in an ultrahigh vacuum (/spl sim/10/sup 11/ torr). Recently, a double magneto-optical trap (MOT) system has been utilized for the first step. In this system, the atoms are first captured in a MOT from a vapor, and then transferred through a thin tube to the second MOT in an ultrahigh vacuum. To transfer the atoms, a pushing beam and a magnetic field are usually required to guide the atoms along the transfer tube. In the paper we report a simple double MOT system which uses neither a push beam nor a magnetic field to transfer the atoms. The atoms are transferred just by gravity. We can collect up to 2 x 10/sup 9/ rubidium atoms in the ultrahigh-vacuum MOT with this system and can achieve the BEC.

Double-clad fiber lasers generate high power performance around several ten watt level CW output. The high brightness compression of about 700 larger than the pumping power was also demonstrated under the high slope efficiency of 73% slope efficiency. The broadband emission caused by the stimulated Raman effect due to the high intensity inside the core propagated in a manner of confined optical propagation. These results showed the great potential of fiber lasers for industrial applications. However, the double clad fiber laser has a limitation about the maximum output because of the finite input area of the first clad. The output of double clad fiber lasers is determined simply by the active volume. We discuss how to expand the potential of fiber lasers to the kW level. We are developing fiber-embedded disk and tube lasers. The pumping scheme of such a type of fiber lasers is side-pumping by LD arrays.

The Z-scan measurement method possessing the simplicity of the experiment set-up as well as the simplicity of the interpretation separately determines the nonlinear changes in index and absorption and has the high sensitivity to all nonlinear optical mechanisms. Thus we performed the experiment varying a repetition rate at 82 MHz, 4 MHz, 800 kHz and 400kHz with a pulse selector in the laser system. We found that the larger the repetition rate was, the more dominant the thermal nonlinearity was in both the nonlinear changes in index and absorption. At the 400 kHz and 800 kHz repetition rate where the samples didn't show thermal nonlinearity, we compared the experiment results with the theory derived from GD (Gaussian decomposition) method. At the 4 MHz and 82 MHz repetition rate where the thermal nonlinearity was dominant we explain the experiment results both qualitatively and quantitatively. The samples were irradiated by Ti-sapphire femtosecond laser with pulse widths of FWHM 100-200 fs. The samples employed for the measurement were CuPc (copper phthalocyanine), CoPc (cobalt phthalocyanine) and ZnPc (zinc phthalocyanine), fabricated in a thin film by a vacuum evaporation.

Alumina ceramic (Al/sub 2/O/sub 3/) has been used for a hard tissue substitution material, such as for artificial joints and tooth roots, because of its high wear-resistance, high hardness and chemical stability. Al/sub 2/O/sub 3/ is, however, a bioinert material and requires mechanical fabrication by a screw cutter to be embedded in a human body. On the other hand, it is well known that calcium phosphate ceramics are bioactive materials. Since hydroxyapatite ceramics [HAp: Ca/sub 10/(PO/sub 4/)/sub 6/(OH)/sub 3/], especially, consist of an inorganic component in bone and have high biocompatibility, they are used as a bony filler. HAp is, however, inferior in mechanical strength. In the medical field, development of a material with both advantages mentioned above is desired. In this study, a simple method using a discharge-pumped KrF excimer laser is presented for formation of a KAp layer on A1/sub 2/O/sub 3/. The bio-compatibility of the sample formed by this method is confirmed with a simulated body fluid (SBF) containing an apatite-wollastonite glass (A-W glass) and the growing mechanism of the KAp layer is discussed.

Optical nonlinearity is being intensively studied for advanced optical functions, such as all-optical switching and wavelength conversion, in future lightwave communications. For transparent operation independent of signal format and data rate, especially usable is partially degenerate four-wave mixing (FWM) in which a new wavelength light (FWM light) is generated from a pump and a signal light. Simultaneous wavelength conversion and phase conjugated wave generation are possible by FWM. In order to obtain high nonlinear efficiency, a waveguide structure is preferable because intense light power is confined in a small area along the length. For this reason, optical fibers and semiconductor optical amplifiers (SOAs) have been mainly utilized as nonlinear devices for lightwave communications. This paper overviews optical nonlinearity (especially FWM) in optical fibers and SOAs. Both fibers and SOAs have advantages and disadvantages. (1) The pump wavelength is automatically determined in a fiber in order to satisfy phase-matching. On the other hand, it can be arbitrarily chosen in SOAs because the device length is short and thus phase-matching does not matter. (2) Fibers have better noise performance because ASE is generated in SOAs. (3) Fibers have flat efficiency over a wavelength range, while SOAs strongly depend on the wavelength separation. This feature is important for simultaneous wavelength conversion. (4) SOAs are preferable from the viewpoint of compactness.

The all-optical wavelength conversion gives flexibilities to the optical fiber communication networks, especially to the wavelength-division-multiplexed (WDM)-based ones, because it allows them to reuse wavelengths and to avoid wavelength channel contentions. Recently, we proposed a novel cross-phase modulation (XPM) wavelength converter that had a directionally-coupled semiconductor optical amplifier (DCSOA) structure, and reported its preliminary results of simulation, in which several unique wavelength conversion characteristics, such as improved extinction ratio, digital-like input-output response, and possibility of polarity-non-inverted wavelength conversion, were predicted. We then fabricated the devices and characterized their static wavelength conversion, where we confirmed the digital response and the extinction ratio enhancement in practice. We present an extremely large nonlinear gain found in the DC SOA, that can potentially be utilized for non-inverted wavelength conversion and digital optical processing. Devices were fabricated by using 1.55 /spl mu/m InGaAsP/lnP multiple quantum wells grown by metal-organic vapor phase epitaxy and by using an optimized self-aligned processes.
