  • Author: Andrew Wells
It has been shown in numerous papers, that the use of ultra-short (<10 fs) pulses has important benefits for two-photon microscopy. With short pulses, the instantaneous peak power for a given average output is much higher. This results in reduced scattering allowing deeper imaging, higher fluorescent efficiency (figure 1) and improved image contrast, all without increasing the photo-damage inflicted on the sample
