      abstract     = {We demonstrate that energetic femtosecond pulses tunable
                      from 1.3 to 1.7 µm can be achieved using self-phase
                      modulation enabled spectral broadening followed by spectral
                      lobe filtering. Based on a home-built 5-W Er-fiber laser
                      system operating at 31-MHz repetition rate, we obtain
                      femtosecond pulses that can be continuously tuned from 1.3
                      to 1.7 µm with >4.5 nJ pulse energy. We further optimize
                      the spectral broadening process using a fiber with larger
                      mode area and scale up the pulse energy to >10 nJ; the
                      resulting pulse duration is as short as ~50 fs. Such a
                      widely tunable, energetic femtosecond source is well suited
                      for driving a laser scanning microscope to perform deep
                      tissue multiphoton microscopy.},
