With higher Ti dopped, shorter laser rod, lower third order group velocity dispersion prism pair, and larger gain modulation operation condition, the laser possesses the potential of generating sub-10 femtosecond.展开更多

Argon ion laser with wavelength of 488 nm was used as light source in the experiments. Field emission microscope diagram showed the formation of three dimensional microstructure. It was found that the amount of photo initiator, the laser intensity and the exposure time are the key factors to obtain well defined three dimensional microstructure.展开更多
