摘要： PURPOSE:To fom an optical mixing part by melting and removing the clad layers and cores of plural plastic-made optical fibers partially through heat-ray irradiation, arranging those optical fibers oppositely, and filling the gap between the cores with a transparent material. CONSTITUTION:Side surfaces of two plastic-made optical fibers 6 and 7 are placed in conatct with each other and irradiated with a laser beam which is smaller than the core diameter of the optical fiber in a direction X in a figure to melt plastic-made cores and clad layers partially, forming the gap A. This gap A is filled with a material which has a refractive index and light transmission loss nearly to those of the core material to form the optical mixing part. Lastly, a clad layer film is adhered to the optical mixing part.

摘要： PURPOSE:To form a junction without decreasing the lifetime of minority carriers by a method wherein an Si oxide thin film layer containing an impurity is formed on a semiconductor substrate, and the thin film layer is heat-irradiated with laser beams which show permeability to the substrate. CONSTITUTION:A PSG film 2 is deposited by CVD method on a mirror-finished surface of the boron doped P type Si single crystal substrate 1 whose one surface has been mirror-finished. Next, when the entire surface of th PSG film 2 is irradiated with a carbonic acid gas laser light 3, the most part of the carbonic acid gas laser light 3 is absorbed into the PSG film 2, the film 2 and only the surface layer of the substrate 1 which contacts the film 2 are effectively heated, and then the impurity is diffused from the PSG film 2 into the substrate 1. At this time, since the laser light 3 is hardly absorbed into the substrate 1, the temperature increase inside the substrate becomes small; accordingly the decrease of the lifetime of the minority carriers of the Si substrate can be prevented.
摘要翻译：目的：通过在半导体衬底上形成含有杂质的Si氧化物薄膜层的方法，在不降低少数载流子寿命的情况下形成结，并对激光束进行热照射，该激光束对基质。构成：通过CVD法将PSG膜2沉积在其表面经过镜面加工的硼掺杂的P型Si单晶衬底1的镜面上。接下来，当用碳酸气体激光3照射PSG膜2的整个表面时，大部分碳酸气体激光3被吸收到PSG膜2中，膜2和仅表面层与膜2接触的基板1被有效地加热，然后杂质从PSG膜2扩散到基板1中。此时，由于激光3几乎不被基板1吸收，所以在底物变小; 因此可以防止Si衬底的少数载流子的寿命的降低。

摘要： PURPOSE:To make a laser light to enter in an optical guide without using a lens by a method wherein a penetrating hole is provided at the central part of a reflector on the outer side of a photo resonator, and one edge of the light guide is inserted therein. CONSTITUTION:One side of the board type part 6 of the metal mirror 5 on the output side is a mirror face 9 facing to the Brewster window 2 of a laser tube 3, and the optical fiber 10 provided with a protective tube 11 is inserted in the hole 8 penetrating the board type part 6 and a connecting part 7. The coupling coefficient of the optical resonator 1 is decided by the diameter of the fiber 10, the reflection coefficient of the edge face thereof and the radius of curvature of a concave mirror 4, and the laser light of output corresponding to the coupling coefficient thereof enters in the fiber 10, and is conducted to the proper place. At this construction, incidence of the laser light in the fiber 10 is enabled effectively only by regulating the angle of the mirror face 9 of the metal mirror 5. Moreover because the reflector on the output side is not needed to transmit the laser light, the metal mirror of low cost can be used, optical loss is reduced according to omission of the lens, and efficiency is enhanced.

摘要： PURPOSE:To improve the efficiency in working, by synthesizing laser beams, dividing the synthesized laser beam and performing multi-point working. CONSTITUTION:A beam splitter 5 is provided near the intersected point of the 1st laser beam 3 and the 2nd laser beam 4 oscillated respectively from a continuously oscillating CO2 laser device 1 and a pulse oscillating CO2 laser device 2. The laser beam 6 multiplex and demultiplex by a beam splitter 5 arrives directly at the working point 9 of the work 8 and is condensed by a condenser lens 7, whereby the working is accomplished. Another laser beam 6' demultiplexed therefrom arrives at another working point 9' of the work 8 from 3 pieces of reflecting mirrors 10 and is condensed by another condenser lens 7', whereby the working is accomplished. The bite of working in the work is thus improved, the ejection of the working debris is accelerated and the satisfactory working is effected with good efficiency.
