We propose a design of an all-fiber laser system that combines the most advanced Er:fiber laser in the telecommunication range and an efficient Yb-doped amplifier for generation of high-power ultrashort pulses. The system is based on nonlinear wavelength conversion of 1.56 μm ultrashort Er:fiber laser pulses to the 1 μm range in a short pigtail of dispersion-shifted silica fiber with subsequent amplification in the Yb-doped fiber amplifier. Pulses with a duration as short as 85 fs and averaged power of 200 mW are demonstrated.

    ABSTRACT: The paper presents a novel design of an all-fiber hybrid erbium laser/ytterbium amplifier system for high power femtosecond pulse generation. Experimental setup consists of a passively mode locked femtosecond Er:fiber oscillator, a diode pumped Er-doped fiber amplifier, a single-mode fiber used as a nonlinear pulse compressor, a silica dispersion shifted fiber (DSF) for wavelength conversion, and a diode pumped two stage Yb-doped high power amplifier. Additionally, a free space grating pair compressor is used to shorten the output pulse to its transform limited duration.

    ABSTRACT: We report a simple all-fiber erbium-doped laser system that is capable of generating 11-fs pulses at a wavelength of 1.7 micron. The setup consists of standard telecommunication components and does not contain photoni crystal fibers commonly used for few-cycle pulse production in the near infrared. We start with a compact polarization mode-locked femtosecond Er:fiber master oscillator delivering pulses centered at 1.57 μm at 49 MHz repetition rate. The pulses are amplified in a forward and backward diode-pumped Er:fiber amplifier to 110 mW and pre-compressed in a single-mode fiber (SMF28) to the 50-fs duration. Next, a short segment (4.5 cm) of highly nonlinear dispersion-shifted fiber (HNL-DSF) is spliced directly to SMF28. The 50-fs pulses are launched into HNL-DSF in the anomalous dispersion regime and experience higher-order soliton pulse compression down to few-cycle duration [1]. To reconstruct the pulse intensity profile we used second-harmonic- generation frequency-resolved-optical-gating (SHS FROG). Reconstructed intensity is shown in Fig 1a, which corresponds to 11-fs pulse duration at FWHM. Taking into account its central wavelength of 1.7 μm it corresponds to two-cycle optical pulse. The optical spectrum, FROG trace, and dispersion profile are shown in Fig. 1b,c,d, correspondingly.

    ABSTRACT: We report a simple all-fiber design of an Er-doped laser system that is capable of generating widely tunable two-cycle pulses. In particular, 13-fs pulses at a wavelength of 1.7 mu m are produced. The mechanism of pulse shortening is identical to the higher-order soliton compression and is supported by modeling based on the slowly evolving wave approximation, which is well suited for down to single-cycle pulse propagation in nonlinear dispersion-shifted fibers.
