Tunable fiber laser source for multi-photon microscopy with MW peak power

Abstract

We demonstrate ultrafast fiber laser source that produces ~100-fs pulses tunable from 940 nm to 1250 nm. More specific, we obtain 120-fs pulses centered at 1150 nm with 105-nJ pulse energy, corresponding to ~1-MW peak power. This femtosecond laser source is ideal for multi-photon imaging in vivo.
