An improved Fresnel waveguide lens is presented. It not only exhibits theoretically excellent focusing characteristics and has almost the same efficiency as that of ideal Fresnel lens, but also simplifies the mask process. We give experimental results concerning these lenes (f/D = 5, 2mm aperture) in silicon nitride waveguides. Nearly diffraction limited focusing characteristics and high efficiency (60%) were experi mentally obtained. The experiment results are in good agrement with theoretical analysis..

Computer simulation shows that the rate of linewidth narrowing is limited by the low cutoff frequency (fc) of feedback loop, because of the FM response of usuall semiconductor laser. Somiclagsical theory analysis shows that not only the narrowed linewidth output can be obtained, but also the limits to fc can be canceled by using two-electrode imhomogenous linewidth enhancement factor semiconductor laser. In this paper we present proposals for improvement..

SUN LAN, XU ZHIZHAN, and ZHANG YIANZHEN
We report the ion measurement of time-of-flight with Faraday cup and the ion energy with a simple analytic model involving an isothermal rarefaction. The targets were polished glass coated with 100A to 1μm of Al and Au foils. Irradiance was varied in the range 1012 to 1014 W/cm2 with constant laser power and variable f
We report the ion measurement of time-of-flight with Faraday cup and the ion energy with a simple analytic model involving an isothermal rarefaction. The targets were polished glass coated with 100A to 1μm of Al and Au foils. Irradiance was varied in the range 1012 to 1014 W/cm2 with constant laser power and variable focal size. Deductions include the scaling relationship of ion velocity at λ = 1.06μm with different focal size, and the anisotropic distributions have been clearly observed..

A conception of thermo-optic switched directional coupler with reversed Δβ is proposed and a testing device with two paires of electric heaters has been fabricated on glass substrate. At 1 kHz square wave voltage modulation, analyzing optical output power from the device by using a high speed 12-bit A/D converter connected with a computer, shows that both a bar-state and a cross-state have been obtained. Because glass waveguides are optical damage-free, polarization-insen sitive, and easy to fabricate, the device can be widely nsed in the oases that do not require high speeds..

The quenching effect of LiF spectrum of C1∏u(v =0, J =53)→X1∑g+(v" = 5, 6: J" =52, 54) for dimer 39K2 by collision of buffer gas Ar was measured experimentally. The relation between the intensities I of LIF spectrum and the pressure P = PAr+PK in beat-pipe oven was deduced by stable collision model. IThe -P plot fitted by this model was in satisfactory agreement with the experimental data. Further analysis of the parameter C1 fitted showed that: the sensitivity of backward detection for heat-pipe oven was 2 times more than that of non-gain fluorescence detection..
