We demonstrated a novel femtosecond frequency-doubled erbium-doped fiber laser with an adjustable pulse repetition rate and its application in two-photon excited fluorescence microscopy. The fiber laser system delivers pulses as short as 60 fs pulses at 780 nm wavelength with 1.35 nJ of energy, corresponding to a peak power of more than 20 kW. The repetition rate is adjusted by built-in pulse picker unit directly providing transform-limited pulses for any chosen repetition rate between 1 and 12 MHz. We employed the laser source to drive a scanning two-photon excited fluorescence microscope for ex vivo rat skin and other samples’ imaging at various pulse repetition rates. Due to compactness, ease of operation, and suitable pulse characteristics, the laser source can be considered as an attractive alternative for Ti:Sapphire laser in biomedical imaging.
