Abstract

The widescale implementation of two-photon polymerization (2PP) is limited primarily due to the cost of high-power femtosecond laser despite the high throughput and superior resolution capability. To reduce the threshold power requirement, a method is developed combining the effect of single photon absorption from a low-cost 532 nm nanosecond fiber laser with the two-photon absorption from an 800 nm femtosecond laser. The effects of spatial and temporal overlap, relative beam sizes, and frequency synchronization are also investigated.
