After over 30 years of advances, multiphoton microscopy (MPM) is now instrumental in a
wide range of in vivo biological imaging applications. However, it has, until recently …

Background Noninvasive assessment of metabolic processes that sustain regeneration of
human retinal visual pigments (visual cycle) is essential to improve ophthalmic diagnostics …

We report a study on pulse dynamics in figure-nine Tm-doped all-polarization maintaining
fiber laser. We analyzed laser operation from self-starting with multi-pulse dynamic to single …

Many experiments in biological and medical sciences currently use multiphoton microscopy
as a core imaging technique. To date, solid-state lasers are most commonly used as …

We report the development of a widely-tunable femtosecond fiber laser system and its
application for two-photon vision studies. The source is based on an Er-doped fiber laser …

In this work, we present a high-power, high-repetition-rate, all-fiber femtosecond laser
system operating at 1.5 m, to the best of our knowledge. By utilizing the soliton-effect-based …

Noninvasive imaging of endogenous retinal fluorophores, including vitamin A derivatives, is
vital to developing new treatments for retinal diseases. Here, we present a protocol for …

Gallium sulfide (GaS), with a hexagonal structure, has received extensive attention due to its
graphene-like structure and derived optical properties. Here, high-quality GaS was obtained …

Significance Two-photon microscopy is used routinely for in vivo imaging of neural and
vascular structures and functions in rodents with a high resolution. Image quality, however …

Multiphoton microscopes employ femtosecond lasers as light sources because the high
peak power of the ultrashort pulse allows for multiphoton excitation of fluorescence in the …
