Item type:Item, 雷射鑽孔過程的熱效應(1976-12) ;黃廣志 ;許隆勝 ;Kuang-Chih HuangLong-Sheng HsuA model that uses a continuous, distributed, and moving heat source to describe the temperature profile for laser-drilled-holes has been developed. A new mathematical approach has been systematically performed in detail. The temperature profile of the laser-formed hole are calculated to indicate the magnitude of thise factors that can influence the process of the removal of materials. A modified CO2 laser system, based on double-pulse-discharge technique [1], has been set up. Using this modified laser system, the experimental results are found to be in agreement with the mathematical analysis.Item type:Item, 雷射全像術在秘密照相上之應用(交大學刊編輯委員會, 1976-04) ;黃廣志 ;張一蕃 ;王遵義 ;K.C.HuangI.F.ChangA rigorous theorem and gedanken experiment for the highly reliable optical modulated method for the confidential picture-taking technology is developed. Its reliability and possibility for realization is also presented in this paper.Item type:Item, 縱向激發二氧化碳雷射之特殊激勵法(交大學刊編輯委員會, 1976-04) ;黃廣志 ;許根玉 ;K.C.HuangK.Y.HsuA new approach, based on a double-pulse-discharge technique, has been successfully performed on a LE CO2 laser. This technique consists of two consecutive discharges. First, the preionization discharge, which is higher in voltage and less energetic. Then, after some delay time, the main discharge follows. TEA laser can perform double-discharge effectively, but it requires auxiliary preionization-electrodes.Double-discharge technique has been only possible for multi-electrode lasers[1]. Now, the new technique developed by us has been demonstrated to be capable of solving the aboved-mentioned difficulty beneficially. The discharge circuit is mainly constructed by using capacitors and spark gaps, and is ready to apply to any two-terminal discharge tube. Comparosons between this device and the same discharge tube[4,5] usinng conventional excitation technique show that the laser energy and overall efficiency can be increased at least by a factor of 1.5, and the optimal E/P ratio was decreased. Furthermore, the improved discharge conditions also enable arcingfree operation with higher pressure than that of applying conventional discharge technique. Up to the present time, this is the only preionization technique for the LE CO2 laser.Item type:Item, The Correlation Between CO2-N2-He Discharge and CO2 Laser(交大學刊編輯委員會, 1974-03) ;黃廣志 ;林緒德 ;祁甡 ;K.C.HuangS.D.LinA self-made CO2 laser system is used to investigate the influence of additive gases on a CO2 laser and the effect of lasing action on a CO2-N2-He discharge. The optimum condition for maximum laser power output is found to be a function of gas mixing ratio, gas flow rate, total pressure, and discharge voltage. When the CO2 laser is lasing, both the discharge current and the electron temperature will decrease due to the fact that the lasing action makes the collisional cross-sections of N2 , CO and CO2 molecules with electrons increase.Item type:Item, Analysis of Low Frequency Fluctuations in an Arc Discharge Column(交大學刊編輯委員會, 1973-02) ;黃廣志 ;鄭珍利 ;K.C.HuangJ.L.ChengThe main objectives of this paper are the theoretical and experimental investigations of low frequency fluctuations in a weakly turbulent plasma generated by a hollow cathode arc discharge. The dispersion characteristics of the weakly plasma turbulence caused by the electro-static ion cyclotron instability was derived. The derivation of the analysis is based on the kinetic model. The experimental observations were found to be in good agreement with our theoretical predictions.Item type:Item, Radial Particle Loss in a Highly Ionized Cylindrical Plasma Column(交大學刊編輯委員會, 1973-02) ;黃廣志 ;K.C.Huang ;K.ChungE.LeviThe statistical properties of the plasma fluctuations in a long plasma column produced by a hollow cathode arc discharge show that there exist different states of weak plasma turbulence. The transition between these states occurs as a results of charges in the confining magnetic field, the background gas pressure, and the boundary conditions. Associated with such transitions are radial changes in the plasma confinement. A sudden jump in the radial particle loss rates is manifested by the increase of the current collected by Buchelnikova ring-collectors and by the change in the radial density profiles measured by electrostatic probes. A linear stability analysis identifies the weak turbulence with the unstable electrostatic ion-cyclotron mode. This mode appears to be unstable in the parameter regions where the inverse gradientlength, k,the perpendicular wave number k⊥ and the ion Larmor radius ρH at the sum temperature Te+Ti are related as1/ρH≧k≧ k⊥. The radial particles loss rate predicted by this analysis agrees with the observed one.Item type:Item, The Elimination of Noise by the Optic Duplex Modulation(交大學刊編輯委員會, 1975-07) ;黃廣志Kuang-Chih HuangThe optic duplex modulation performed by using two kerr cells at the optic transmitter. The signals are recoverable at the receiver by using photodetector to respond the appropriate polarization components of light. The application of duplex modulation is to eliminate the noises due to atmospheric turbulence. The results of experiments shows that the atmospheric turbulent noises are really eliminated by the method. Finally the advantages and disadvantages to use kerr effect rather than pocket effect for optic modulation system are compared.Item type:Item, The Inexpensive Repetitively Pulsed CO2 Laser(交大學刊編輯委員會, 1975-07) ;黃廣志 ;李大為 ;張一蕃 ;K.C.HuangDavid LeeExperiments were performed to obtain inexpensive construction of repetitively pulsed CO2 lasers. A 2.2 cm bore,150 cm discharge tube containing CO2 and N2 gas mixture was operated at 24 KV to produce output in excess of 0.1 joule. The output was approximately doubled when He gas was used along with CO2,N2 gases. At maximum output energy the ratio of electric field to pressure was approximately 20 V/cm torr. Good control of discharge and high circuit efficiency was obtained with a simple circuit operated at 30 or 60 pulses per second synchronized to the 60 Hz power line.Item type:Item, On Chiao Tung University's Laser Holographic System(交大學刊編輯委員會, 1974-03) ;黃廣志 ;吳國誠 ;K.C.HuangK.C.WuThe first laser holographic system in our country has been set up at the National Chiao Tung University. The main objective of this research notes is two folds: one is to show that we are able to make all kinds of holograms such as Leith-Upatniek hologram, and volumu hologram only by means of a simple set-up. he other is to present some technique information which could not be easily found in the journals. It can be sure that this information wold be very useful to the people who are interested in engaging in works of this field.
