Title: Optical path converter used for linear array laser diode and laser device using the same and its production
Inventor: YAMAGUCHI SATORU
IPC: G02B27/09
Filed: 1994-04-28
Abstract: PURPOSE:To provide the semiconductor laser device which is increased in energy density at the focus of the semiconductor laser, the optical path converter which is capable of increasing the energy density by extremely diminishing the focus of the linear array semiconductor laser device and the powerful semiconductor laser excited solid-state laser device for which the semiconductor laser device is used. CONSTITUTION:Dotty laser beam groups are disposed on the front surface of a linear array laser element 10 and the laser beam groups refracted and collimated in a direction nearly perpendicularly to the direction of the dot lines thereof are received and are radiated by perpendicularly rotating the direction of the laser beams from the respective emitters or the respective emitter groups, by which the laser beams are converted to substantially ladder- shaped laser beam groups. These substantially ladder-shaped laser beam groups are independently collimated in two directions and are converged to the focus, by which the density of the laser energy at the focus is improved. Such laser energy is used as the exciting source of the semiconductor laser excited solid- state laser device.

Filed: 1993-05-18
Abstract: PURPOSE:To restrain influence of noise caused by external induction and radiation noise generated in another apparatus, by wrapping outer conductor with magnetic material, on the inner side of the connection position of the outer conductor and shielding conductor in a master apparatus, and increasing the inductance of the outer conductor up to a specific value. CONSTITUTION:When induction noise from the outside is applied to a subordinate apparatus 11, the noise current passes a connected cable 2, flows to a master apparatus 1, travels an FG ground, and reaches the earth. The noise current flows through outer shielding conductor 23 of the cabel 2, and scarcely permeates until outer conductor 22 of the inner layer, so that noise influence is not exerted at all on the apparatuses. On the other hand, when induction noise is applied to the master apparatus 1, the noise current is immediately earthed from the FG ground, and does not exert influence on the inside of the subordinate apparatus 11. Noise generated in the inside of the subordinate apparatus 11 makes a noise current flow through the R side of a main circuit, which current flows through the outer conductor 22 of the grounded cable 2 and reaches the master apparatus 1. This noise current flows through the outside of the outer conductor 22 and the inside of the shielding conductor 23, and scarcely exerts influence on conductor 21.
