Bottom Line: Simultaneous spatial temporal focusing (SSTF) is used to deliver microjoule femtosecond pulses with low numerical aperture geometries (<0.05 NA) with characteristics that are significantly improved compared to standard focusing paradigms.Nonlinear effects that would normally result in focal plane shifts and focal spot distortion are mitigated when SSTF is employed.As a result, it is shown that SSTF will enable surgical implementations that are presently inhibited.

g001: The simultaneous spatial temporal focusing geometry.

Mentions: The optical arrangement for SSTF must produce a beam with a transverse spatial chirp (collimated frequency components) along with collimated beamlets. In most of our experiments, we employ the SSTF geometry described in [9,10], shown in Fig. 1Fig. 1
