摘要： A quantum cascade laser 1, which generates infrared light or other light of a predetermined wavelength by making use of intersubband transitions in a quantum well structure, is arranged by forming, on a GaAs substrate 10, an AlGaAs/GaAs active layer 11 having a cascade structure in which quantum well light emitting layers and injection layers are laminated alternately. Also, at the GaAs substrate 10 side and the side opposite the GaAs substrate 10 side of active layer 11, is provided a waveguide structure, comprising waveguide core layers 12 and 14, each being formed of an n-type GaInNAs layer, which is a group III-V compound semiconductor that contains N (nitrogen), formed so as to be lattice matched with the GaAs substrate 10, and waveguide clad layers 13 and 15, each formed of an n++-type GaAs layer. A quantum cascade laser, with which the waveguide loss of generated light in the laser is reduced, is thereby realized.

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 microparticle dispersion liquid manufacturing apparatus 10 includes a controller 11, a light source 12, an irradiation optical system 13, and a container 14. A solid object 1 is contained in and a solvent 2 is injected into an interior of the container 14 to enable attainment of a state where the solid object 1 is in contact with the solvent 2. The light source 12 repeatedly outputs pulsed light. By repeatedly irradiating the solvent 2 with the pulsed light from the light source 12, expansion and contraction of the solvent 2 is made to occur repeatedly at the irradiated portion, thereby generating a pressure wave in the solvent 2, and the pressure wave is made to act on the solid object 1 to finely pulverize the solid object 1 and thereby manufacture a microparticle dispersion liquid in which microparticles are dispersed in the solvent. A microparticle dispersion liquid manufacturing method and manufacturing apparatus are thereby realized by which both suppression of impurity formation and an increase in efficiency of microparticle formation can be achieved readily.
