Optical Comb Peculiarities of High-energy Chirped-pulse Erbium-doped All-fiber Ring Laser

We have studied optical comb peculiarities of a high-energy chirped-pulse Er-doped all-fiber laser. A relatively low repetition rate of ~ 7.9 MHz with signal-to-noise ratio ~ 69 dB and a pulse width of 24.6 ps was achieved. To characterize the short-term stability of the obtained regime we have meas...

Description
Summary:We have studied optical comb peculiarities of a high-energy chirped-pulse Er-doped all-fiber laser. A relatively low repetition rate of ~ 7.9 MHz with signal-to-noise ratio ~ 69 dB and a pulse width of 24.6 ps was achieved. To characterize the short-term stability of the obtained regime we have measured the relative intensity noise of the laser, which is < -107 dBc/Hz in the range of 3 Hz -1 000 kHz. The output average power is ~15 mW which corresponds to ~ 77 W peak power and ~1.9 nJ pulse energy.
