| Research Abstract |
(1) The construction of the optical system for optical trap and laser lithography
Two YAG lasers (1064nm wavelength, 500mW) for optical trap, and a He-Cd laser (325nm wavelength, 20mW) for laser lithography were used. The microstructure objects are freely moved, fixed, and molded by laser in the optional position. Manipulation under the microscope is possible and it is recorded by the digital camera.
(2) The optical trap of micro spheres on the UV photopolymer resin liquid
Following microstructure objects were fabricated by putting micro spheres on the UV photopolymer resin liquid, and doing the optical trap.
(a) It was possible to fix the minute sphere to the column which is perpendicularly extended on the slide. This system is effective for the construction of the micro optical system of the sphere lens.
(b)It was possible to fix the minute sphere to the optical fiber tip. This system is effective for raising optical incidence efficiency to the optical fiber.
(3) The optical trap of the droplet of the UV photopolymer resin
It succeeds in doing the optical trap of micro droplet itself of the UV photopolymer resin. This droplet trappedby laserwas used as adhesive for micro objects. Micro droplet was transported and was fixed for combining the micro spheres. Doing similar processes, several micro spheres were connected.
(4) Laser driven microstructure objects
Polystyrene latex sphere coupled optical trap was driven by laser. Polystyrene latex sphere on the cantilever beam fabricated by laser lithography was vibrated photothermally.
However, the cantilever beam of the single-mode optical fiber was not driven because of weakness of laser intensity.
In the future, the optical system of which the three-dimensional trap is possible must be constructed for the fabrication of practical microstructure objects.
