Abstract: PURPOSE: To increase yield and increase the opening diameter by forming an intermediate plate of a metallic material different from materials of the upper layer plate and the lower layer plate. CONSTITUTION: An orifice plate 11 comprises a lower layer plate 112, an intermediate plate 114 and a upper layer plate 118 that are laminated in that order. The lower layer plate 112 is provided with a plurality of supply openings 1, 2 for supplying two or more different liquids. The upper layer plate 118 is provided with a nozzle 3 for ejecting a mixture liquid obtained by mixing two or more different liquids. The intermediate plate 114 is disposed between the lower layer plate 112 and the upper layer plate 118. The intermediate plate 114 is formed of a laminate of a first plate 114a and a second plate 114b. The second plate 114b of the intermediate plate 114 is formed of a metallic material different from the material of the lower layer plate 112 and the material of the upper layer plate 118, thereby increasing yield, and increase the opening diameter.

Abstract: PURPOSE:To easily but firmly fix each member while a high alignment accuracy is being maintained between each member. CONSTITUTION:A semiconductor laser chip 1 is attached to a fixed substrate 11 through the intermediary of a heat sink 3, and an LN-X wavelength conversion element 6 is attached through an orthogonal member 20. At this time, liquid metal 60, which is mainly composed of gallium and indium, is coated between the fixed substrate 11 and the member 20 and also between the LN-X wavelength conversion element 6 and the member 20, they are left alone in that state for five minutes to several hours, and they are allowed to show an alloying reaction. As a result, each member can be fixed.

Abstract: PURPOSE:To stably guide a fundamental-wave laser beam to an optical waveguide in an optical-waveguide element by a method wherein, in a state that the optical waveguide in the optical-waveguide element has been brought close to the edge of a semiconductor laser device, the main face of the optical- waveguide element is arranged and fixed perpendicularly to the main face of a substrate. CONSTITUTION:In a state that a proton-exchange optical waveguide 4 has been brought close to the edge of a semiconductor laser chip 1, the main face 21 of an LN-X wavelength conversion element 6 is arranged perpendicularly to the main face 22 of a fixed substrate 11. Concretely, a member 20 which is composed of Cu, a ceramic or the like and which is provided with a right angle is installed so as to come into contact with the LN-X wavelength conversion element 6 and with the fixed substrate 11, and it is arranged on, and fixed to, the fixed substrate 11 in a state that the LN-X wavelength conversion element 6 has been attached to the member 20. Thereby, it is possible to stably guide a laser beam from the semiconductor laser device 1 to the optical waveguide 4.

Abstract: PURPOSE:To improve the yield in a polarization inversion process and to improve productivity by subjecting a ferroelectric crystal to a heat treatment in a uniform stress loading state and executing the polarization inversion. CONSTITUTION:Striped Ti layers 7 are formed on the ferroelectric crystal 4 consisting of a single crystal substrate of single-domained LiNbO3. This ferroelectric crystal 4 is imposed via a support 3 in a sample base 1 and a load imparting body 5 is imposed thereon via the support 3. This support 3 uniformly loads the stresses to the ferroelectric crystal 4 by its wire-shaped front end part. The polarization inversion is periodically executed in this state by an ordinary Ti diffusion method, i.e. heating, to obtain the periodic domain structures. The polarization inversion is accelerated in this way and the fluctuationed in the polarization inversion by the fluctuations of the ferroelectric crystal wafers and crystal lots are decreased in this way and the workability and yield are improved.

Abstract: PURPOSE:To eliminate the need for impression of a voltage and to avoid the failure in a crystal generated by the flow of current and the degradation in purity by the diffusion of an electrode material by disposing absorbers or reflectors of electromagnetic waves for heating a nonlinear ferroelectric optical material to be formed with domain inversion structure parts on one main surface of this optical material. CONSTITUTION:The substrate of a Cherenkov radiation type light second harmonic wave generating element having the periodic domain inversion structure parts is constituted of the crystal of lithium niobate having a large nonlinear coefft. and a C-axis in the thickness direction of the crystal at the time of forming the above-mentioned element. Namely, the optical material 1 formed as the single domain having the C-axis in the thickness direction is prepd. The material is heated up to the temp. below the Curie point thereof. for example, up to about 1,200 deg.C and the external DC voltage is impressed in the thickness direction thereof to generate the domains unified in the thickness direction of the C-axis at the time of forming the above-mentioned material as the single domain. The absorbers or reflectors 2 consisting of Pt having the heat resistance to heat rays for heating are previously provided in the form of stripes on one main surface 1a of material 1 and the polarization inversion is generated by the voltage generated by the pyroelectric effect.
