JOURNAL FREE ACCESSThis paper deals with the characteristics of glow discharge for high power cw CO2 laser excitation. It is found that J/P2 (J: current density, P: gas pressure) on the cathode surface has the constant value of 6.25×10-3 mA/Torr2-cm2 for the Mo cathode. The CO2 dissociation in the gas mixture is dominated by the phenomena near the cathode, since the steady-stage CO2 concentration after discharge closely depends on the kind of cathode materials The discharge gap length gave the effect on the maximum discharge power. The optimum gap length was about 4 cm at the pressure of 100 Torr. For the gap length above 4 cm, type of the silent-discharge assisted glow discharge is recommended.View full abstractDownload PDF (797K) -

JOURNAL FREE ACCESSThe pockels effect in potassium dihydrogen phosphate (KDP) and ammonium dihydrogen phosphate (ADP) was measured by laser appling impulse voltage. Then mechanical vibration of KDP and ADP were observed to photoelastic effect. The unclamped photoelastic coefficients were obtained as II (ADP) =2.6X10-13, II (ADP) =1.0×10-12 m2/N. The effect of suppression to vibration by using load of weight and steel coil spring was proportion to subtract load par two square root from tension of inverse-piezoelectric effect.View full abstractDownload PDF (770K) -

JOURNAL FREE ACCESSAn innovative scheme of inertial fusion is introduced in which the plasma pressure is contained by a metallic shell while its heat is contained by a magnetic field. The scheme utilizes a self-generated, force-free magnetic field of≥102 T in a plasma with a density of-1021 cm-3 and a temperature of-10 keV which are produced by a laser and/or a particle beam in a hard electrically conducting shell. This new scheme can resolve some fundamental difficulties encountered in both magnetic and inertial fusions.View full abstractDownload PDF (1020K) -

JOURNAL FREE ACCESSNd3+-doped LiYF4 single crystals are grown by the Czochralski technique, which have dimensions of 20 mm in diameter and 120 mm in length. The effective distribution coefficient is found to be about 0.29. The laser performance of a grown crystal is also discussed.View full abstractDownload PDF (742K)
