ジャーナル フリーPhoton transport equations, which describe the growth of laser pulse propagating an amplifying medium, cannot be solved in closed form when a loss term is taken into account. In the previous paper, a numerical analysis was given for the equations with certain initial and boundary conditions by using the method of finite difference. However the existence of the solution and convergence of the difference scheme were not proved but assumed there.
Here we prove mathematically the unique existence of the solution in the photon transport equations when loss term is not negligible. This paper also give the outline of the proof of convergence in the upper difference scheme. The result of these proofs advances the degree of reliability of solutions calculated by the finite difference method.抄録全体を表示PDF形式でダウンロード (637K) -

ジャーナル フリーSpeckle interferometers using digital image processing techniques are described. The systems consist of interferometric optical setups and a digital TV-image processing facility with a large frame memory. The digital facility allows us to perform precise and flexible operations such as subtraction, summation, and Level slicing of TV-images. The interferometers make it easy to measure in quasi-real-time surface deformations and modal vibration amplitude of objects. Digital image processing techniques easily generate high contrast fringes. Some experimental results are presented.
A statistical theory is applied to analyze the fringe formations due to 3-D displacements of objects for various types of speckle interferometers. Interpretation of the results leads to conditions of maximum fringe contrast and the limitation of the measurements.抄録全体を表示PDF形式でダウンロード (1131K) -

ジャーナル フリーA computer simulation code for UV-periodized discharge Kr F lasers is developed, including time dependent circuit equations and kinetic rate equations for various atomic and molecular species, electrons and photons. The energy distribution of electrons are calculated with a Boltzmann code. The laser characteristics computed by this code are compared with those of a home-made Kr F laser, and the energy loss mechanism is investigated for the variation of the input voltage, the total gas pressure, and the size of the active medium. The results are qualitatively in good agreement with those of experiment except the absolute output energy. This disagreement is maybe caused by the non-uniform distribution of the discharge. The most important loss effective to the over-all efficiency is the circuit loss by impedance mis-matching. The scalability of these self-sustained discharge excimer lasers is briefly discussed with this simulation code.抄録全体を表示PDF形式でダウンロード (1649K) -

ジャーナル フリーA new technique for fabrication of a double shell target was developed using a removable paraffin mandrel. The outer shell was parylene (160-260μm in diameter, 4-10μm in wall thickness) and the inner shell was a glass microballoon (80-160μm in diameter, 1-4μm in wall thickness). Arbitrary gases can be loaded between the outer and inner shells. Detail technique and problems to be improved are reported.抄録全体を表示PDF形式でダウンロード (911K) -
