“The FemtoFiber ultra 920 was a pleasure to work with: it is incredibly compact and easy to use, and lowers the barrier to entry for two-photon microscopy. In particular, I appreciated the added features like integrated dispersion compensation and power control as they minimise the extra effort I need to put in when setting up a 2P microscope. Having years of experience in multiphoton microscopy, I feel that lasers like this one that we can just „plug and play“ will be game-changers for the field.“

„The inherent stability, the ease of use, and the clean temporal pulse shape of the FemtoFiber ultra 920 make TOPTICA‘s fiber lasers the ideal choise for our applications in neuroscience“

„For me the FemtoFiber ultra 920 with its Clean-Pulse Technology has the perfect optical parameters for highest two-photon image quality. In addition, the passive and cold laser head is an essential feature since it reduces the noise in laboratory and with that the stress on the living animals“

“I recommend the FemtoFiber ultra 920 and FemtoFiber ultra 1050 to other colleagues because both are reliable, easy to use, plug and play, with specifications that perfectly fit our purpose, no vibration on the optical table, no chiller noise, and last but not least because of the great support from TOPTICA.”
