Multiphoton microscopies are an invaluable tool in biomedical imaging given their inherent capabilities for label free imaging, optical sectioning, chemical and structural specificity. They comprise various types of Coherent Raman microscopies (CR), such as Coherent Anti-Stokes Raman Scattering (CARS), Stimulated Raman Loss (SRL) or Stimulated Raman Gain, different kinds of Harmonic Generation imaging (HG) such as Second and Third Harmonic Generation (SHG and THG respectively), and Multiphoton Autofluorescence imaging (MA) such as Two and Three Photon Excited Autofluorescence (TPEAF and ThPEAF respectively). Despite their significant advantages, multiphoton microscopies, comparably to all other types of optical microscopies, exhibit limited penetration depth in tissue due to absorption and scattering. In this work we explore the advantages of multiphoton microscopies in hard and soft deep tissue imaging when using excitation wavelengths in the range of Short-Wavelength Infrared (SWIR) windows which occur between 1000 nm and 2500 nm. These spectral windows have notable merits including longer attenuation lengths and none or very low signal absorption observed for almost all kinds of multiphoton microscopy. We show results of using excitations in the SWIR windows, generated by standard as well as novel sources, such as a thulium fibre laser, in different types of multiphoton microscopy on a variety of hard and soft tissue samples (bone, cartilage and other tissue types) and demonstrate the advantages of using excitations in this wavelength range, including longer penetration depth and high resolution for deep tissue imaging.
