Multiphoton microscopy is a branch of optical microscopy, which unlike conventional fluorescence microscopy which uses single photons of high energy (typically in the ultraviolet or visible spectrum) to excite fluorophores, uses two or more lower-energy infrared photons to excite the fluorophores.

Fiber lasers are well-suited for this application due to their ability to produce ultrashort, high-intensity pulses in the near-infrared range, which are ideal for deep-tissue imaging. Their excellent beam quality, stability, and compact design make them easy to integrate into microscopy systems, providing reliable and precise performance for high-resolution, three-dimensional imaging of biological specimens.

Our ultrafast mode-locked lasers are available in a wide range of wavelengths in the visible and NIR regime. These models are compact and require minimal maintenance.
