Abstract

We report on stable stretched-pulse generation with a pulse duration (at FWHM) $\sim 180\mathrm{fs}$ at a central wavelength of 1560 nm with an average output power of 30 mW at a repetition rate of $\sim 11.3\mathrm{MHz}$ (with the signal-to-noise ratio at a fundamental frequency $\sim 59\mathrm{dB}$) with an Allan deviation of a pulse repetition frequency of $\sim 5.75·{10}^{-9}$ for a 1 s interval and a relative intensity noise of $<-101\mathrm{dBc}/\mathrm{Hz}$$<-101\mathrm{dBc}/\mathrm{Hz}$ (30–1000 kHz). This corresponds to a $<14.7\mathrm{kW}$ maximum peak power and a $<2.6\mathrm{nJ}$ maximum available pulse energy obtained immediately from the highly nonlinear all-fiber laser resonator.
