“…High repetition rate femtosecond lasers play an important role in many applications, including optical arbitrary waveform generation [1,2], high-precision frequency metrology [3,4], ultrastable microwave signal generation [5][6][7], high-speed optical sampling [8][9][10], and high-resolution astronomical spectrographs (astrocombs) [11][12][13][14]. Over the past decade ultrafast lasers of multi-gigahertz repetition rates have been experimentally developed [15][16][17][18][19][20][21][22][23][24][25][26][27].…”

A passively mode-locked fiber laser with 1.03 GHz fundamental repetition rate and low noise performance is demonstrated. The compact and robust laser operates at a central wavelength of 1553.9 nm with a 3 dB spectral bandwidth of 7.9 nm and a temporal width of 550 fs. All the fibers and components used in the laser are polarization-maintaining (PM), so the output pulses are linearly polarized. The degree of polarization (DOP) of the optical pulses is measured to be 0.9994. The phase noise of the seventh harmonic (7.21 GHz) is measured and a low timing jitter of 11.7 fs is obtained by integrating the phase noise from 30 MHz down to 100 Hz. The noise performance is detailed analyzed and the methods for further optimizing the timing jitter are also proposed. So far as we know this is the first reported low noise all-PM erbium-doped fiber (EDF) laser with gigahertz level pulse repetition rate.
