Paper Abstract

We propose a holographic spatiotemporal lens to improve spatial resolution of two-photon excitation spot as a new focusing technique of femtosecond laser pulse. Femtosecond laser pulses dispersed by a diffraction grating are irradiated to a chirped diffractive lens displayed on a spatial light modulator. The chirped diffractive lens has a spatially chirp of focal length for a design for its corresponding wavelength. The shortest pulse was experimentally obtained only at the focal plane. The pulse duration was also supported with a computer simulation.
