Research Abstract

Carrier envelope phase stabilized ultra-short laser pulse (2mJ/pulse, 6fs, 5kHz, ~200 mrad) was generated from high repetition high power femtosecond laser system for developing the multi-photon microscope by using the differentially pumped neon filled hollow fiber pulse compressor. For compensating the positive dispersion using objective lens of the multi-photon microscope, nine high-dispersive negative chirped mirrors and high refractive index (SF57) prisms were used and it was confirmed that the pulse duration can be minimized at the sample of the multi-photon microscope.
