Abstract:

We have acquired the femtosecond laser system Tsunami from Spectra Physics, CA, 89,900 pumped by a DPSS laser Millennia54,500 , also from Spectra Physics, CA, and used them for developing multi-photon process based technologies. It is known that two-photon excitation produces highly localized effect near the focal point when the pump beam is focused by a lens. This property can be used to achieve excellent depth resolution to create a highly localized two-photon initiated process at different depths, with a very well defined depth control. This feature provides an unique opportunity to develop such diverse applications as for 3D volume imaging, 3D optical circuitry fabrication, high density 3D optical data storage, etc. In this context we were using the newly acquired laser system Ultra-short pulse, high repetition rate TiSapphire laser, Tsunami pumped by a diode pumped solid state laser, Millenia for two-photon confocal microscopy and spectroscopy, two-photon initiated micro-fabrication and two-photon optical datastorage. We were able to use this new laser system with our confocal micro- spectroflourimeter as well as for fabricating 3D optical circuitry.
