    Optical transmittance properties of M1, M2 and M3.
    Maximum average output power at different repetition rates (0.1, 600, 1000, 2000, 3000, 4000 and 5000 kHz). The inset shows the average output power versus absorbed pump power at repetition rates of 0.1 and 5000 kHz.
    Narrowest pulse width at different repetition rates (0.1, 600, 1000, 2000, 3000, 4000 and 5000 kHz). The inset shows the spectrum at 0.1 kHz.
    Maximum single-pulse energy at different repetition rates (0.1, 600, 1000, 2000, 3000, 4000 and 5000 kHz).
    Maximum peak power at different repetition rates (0.1, 600, 1000, 2000, 3000, 4000 and 5000 kHz).
    Single-pulse and typical pulse train (inset) at the repetition rate of 0.1 kHz.
    Typical pulse trains at different repetition rates (600, 1000, 3000, 4000 and 5000 kHz).
    Stability of maximum average output power at different repetition rates (0.1, 3000 and 5000 kHz).
