摘要： A dental therapy apparatus which enables a dental therapy more surely and less invasively is provided. A dental therapy apparatus (10A) comprises a laser light source (11) emitting laser light (L) having a wavelength within a wavelength region of 5.7 to 6.6 μm; a controller (12) pulse-driving the laser light source and controlling at least one of pulse width and repetition frequency of pulsed laser light emitted from the laser light source; and an irradiation optical system for irradiating a tooth (20) including a carious part (21) with the light emitted from the laser light source. In this dental therapy apparatus, the controller controls at least one of the pulse width and repetition frequency of the pulsed light, so as to selectively cut the carious part (21).

摘要： A semiconductor laser bar 2 is mounted onto a liquid-cooled heat sink 1. A molybdenum reinforcement member 3 is fixed onto the surface opposite to the surface on which the semiconductor laser module 2 is mounted. The molybdenum has a linear expansion coefficient less than that of the heat sink 1. Sub-mounts are preferably made of a Cu—W alloy, more preferably of the reinforcement member 3 molybdenum. In this case, the stresses that are imposed on the heat sink 1 when being expanded or contracted can cancel each other out.

摘要： A plasma shutter forming apparatus for forming a plasma shutter used in a system configured to generate and accelerate radiations by irradiating a target with a laser pulse and generating a high-density plasma for blocking the laser pulse which is returned as a feedback light to upstream of the system without being absorbed by the high-density plasma, including a plasma shutter generating target, and a plasma shutter triggering laser irradiator, wherein the laser pulse from the plasma shutter triggering laser irradiator is directed to the plasma shutter generating target to generate the high-density plasma and form the plasma shutter, thereby blocking the laser pulse which is returned as the feedback light. Optics are prevented from becoming damaged by feedback light reflecting when generating the high-density plasma in a laser-driven radiation generating system and returning back to the upstream of the laser system.

摘要： In an active layer 15 of a semiconductor laser device 3, a refractive index type main waveguide 4 is formed by a ridge portion 9a of a p-type clad layer 17. Side surfaces 4g and 4h of the main waveguide 4 form a relative angle θ, based on a total reflection critical angle θc at the side surfaces 4g and 4h, with respect to a light emitting surface 1a and a light reflecting surface 1b. The main waveguide 4 is separated by predetermined distances from the light emitting surface 1a and the light reflecting surface 1b, and optical path portions 8a and 8b, for making a laser light L1 pass through, are disposed between one end of the main waveguide 4 and the light emitting surface 1a and between the other end of the main waveguide 4 and the light reflecting surface 1b. The optical path portions 8a and 8b are gain type waveguides and emit light components L2 and L3, which, among the light passing through the optical path portions 8a and 8b, deviate from a direction of a predetermined axis A, to the exterior. A semiconductor laser device and a semiconductor laser device array that can emit laser light of comparatively high intensity and can reduce side peaks are thereby realized.

摘要： The present invention relates to a fuel cell including: a membrane electrode assembly (2) having a fuel electrode (13), an air electrode (16), and an electrolyte membrane (17) sandwiched therebetween; and a fuel storage unit (4) storing a liquid fuel. The fuel cell is capable of continuously generating electricity for long hours only by being replenished with a fuel, and therefore, attempts have been made to miniaturize the fuel cell to use it as a power source of portable electronic devices. When the membrane electrode assembly and the fuel storage unit in the fuel cell are connected via a flow path, a fuel supply state becomes uneven depending on the shape and the like of the flow path even though a supply amount of the fuel can be adjusted, which causes a problem such as a decrease in an output of the fuel cell. The present invention solves the aforethe problem by providing, in the fuel cell, a fuel distributing mechanism (3) which supplies the fuel to a plurality of places of the fuel electrode, and connecting the fuel distributing mechanism and the fuel storage unit via the flow path (5).

摘要： A laser apparatus 10 includes: a laser medium 11 arranged between a pair of reflecting means 12A and 12B of an optical resonator 12 and adapted to be excited to emit light; a saturable absorber 14 arranged on the optical axis L of the optical resonator 12 between the pair of reflecting means, the transmissivity thereof being adapted to increase with the absorption of emitted light 21 from the laser medium; and an excitation light source unit 13 adapted to output light 22 having a wavelength that excites the laser medium. The saturable absorber 14 is a crystalline body having first to third mutually perpendicular crystallographic axes and is arranged in the optical resonator 12 in such a manner as to have different transmissivities for emitted light in two mutually perpendicular polarization directions. In this case, a laser oscillation occurs for emitted light in the polarization direction that shows the greater transmissivity, and it is therefore possible to obtain laser beams having a stabilized polarization direction.
