Multiphoton microscopy at an excitation wavelength of 1.26 µm

Abstract : We present a multiphoton microscope using a Cr4 + :forsterite femtosecond laser with an emission wavelength of 1260 nm for the excitation of the multiphoton processes. This wavelength is well adapted to the "optical window" in biological tissues and permits to reach higher imaging depths than systems using more conventional titanium:sapphire laser sources. The paper describes the experimental set-up and reports on first results on human cornea and skin samples.
