Abstract :
We investigate the efficacy of inducing reproductive death of cancer cells by ultraviolet, visible and near infrared femtosecond laser pulses. The reproductive cell death may result from (numerous) single photon absorption events or from multi-photon absorption processes. The high intensity of femtosecond laser pulses facilitate multi-photon processes, which potentially may arrest the reproduction of cells at wavelengths that otherwise are harmless.
