Abstract: A microparticle trapping device includes: a fluid channel configured to be injected with a fluid including a microparticle; first and second electrodes configured to generate an electric field in the fluid channel; and an electrical insulator formed with at least one opening between the first and second electrodes in the fluid channel. The electrical insulator is disposed between the first and second electrodes so that an inhomogeneous electric field is made through the at least one opening between the first and second electrodes in the fluid channel, and the still other aspect is configured to trap the microparticle through dielectrophoresis.

Abstract: Disclosed is a laser device including: a laser light source configured to emit laser light; a phase control unit configured to receive the laser light emitted from the laser light source, to control a spatial phase of a portion of the laser light, to emit the portion of the light as control light, and to emit another portion of the laser light as non-control light; a first optical system configured to irradiate an object with the control light emitted from the phase control unit; a detector configured to detect the non-control light emitted from the phase control unit; a second optical system configured to cause the non-control light emitted from the phase control unit to converge toward a detection surface of the detector.
