Abstract

The lemtosecond laser technology is successfully combined with the laser-scanning microscope technology to OI)Cfl up the new world of three-dimensional microscale optics. We have proposed the use of Iemtosecond micro-structure in photopolvmerizahle resin[ 1. 2. Figure 1 shows a collection of photographs ol microstruCtureS made by a laser. Micron scale tube, coil, and funnel are solidified in photopolymerizable resin as a focused beam of infrared pulse laser runs three dimensionally in the resin according to the computer-programmed sequence. Only the beam focus where photon density is high enough. two photons of near infrared are coherently absorbed by the ultraviolet-sensitive photopolymerizable monomer/oligomer. resulting in local solidification of resinlSee Fig.2. The structure is extracted from the resin by removing unsolidified resin with ethanol. To enhance the square law in intensity of two-photon process, a high peak OWCF during the pulse is required for laser, while the mean power should he moderate. We used a Titanium Sapphire laser at 7)0nm with l6Ofsec with the peak power of 50kw. Figure 3 shows the absorption spectrum of the resin (SCR-500: Japan Synthetic Rubber Co.. Ltd.) which we used.
