“…2(d) soliton period is on the same order as the cavity length, the second order dispersion coefficients for the SMF-28e+ and the gain fiber can be determined as -85 fs 2 /mm and -150 fs 2 /mm, respectively. These values are similar to previously published data [16], [30]. With a group delay dispersion of the SBR around -100 fs 2 for the center wavelength of 1968 nm (according to the provided datasheets), the total round-trip cavity dispersion amounts to -0.06 ps 2 .…”

We demonstrate a single-mode Tm/Ho co-doped mode-locked fiber laser with a repetition rate of 253 MHz that is directly core-pumped at a wavelength of 790 nm. In a solitonmode-locked linear fiber laser cavity, femtosecond pulses with a transform-limited pulse durations of 315 fs are generated. With single-mode core-pumping the high peak absorption of the gain medium is utilized to obtain an optical spectrum with suppressed ripples and high signal-to-background levels in the RF spectrum above 70 dB. Good noise performance with a rms relative intensity noise of 0.11% [10 Hz, 2 MHz] and a timing jitter of 20 fs [100 Hz, 2 MHz] is demonstrated. For a single pulsing mode-locking regime, a reproducible and stable peak wavelength tunability of the optical spectrum is achieved over 11 nm by pump power tuning.

“…A 90:10 fiber coupler is employed to extract 90% power from the laser cavity. The anomalous dispersion of the TDF and the SMF-28 are about −91 and −70.8 ps 2 ∕km at the 2 μm band [20]. The pigtail fiber from the passive components is approximately 3.7 m in total, neglecting the length of the components themselves.…”

A mode-locked thulium-doped fiber laser (TDFL) based on nonlinear polarization rotation (NPR) with different net anomalous dispersion is demonstrated. When the cavity dispersion is −1.425 ps 2 , the noise-like (NL) pulse with coherence spike width of 406 fs and pulse energy of 12.342 nJ is generated at a center wavelength of 2003.2 nm with 3 dB spectral bandwidth of 23.20 nm. In the experimental period of 400 min, the 3 dB spectral bandwidth variation, the output power fluctuation, and the central wavelength shift are less than 0.06 nm, 0.04 dB, and 0.4 nm, respectively, indicating that the NPR-based TDFL operating in the NL regime holds good long-term stability.

“…To satisfy this need, we are developing a modelocked Tm/Ho fiber laser to serve as a seed source to generate a supercontinuum to extend from 2 to 3 m in a ZBLAN fiber. First, we demonstrated a selfstarting, passively mode-locked Tm/Ho co-doped fiber laser that lases at one of two center wavelengths [20]. Mode-locking is obtained via nonlinear polarization rotation using a c-band polarization sensitive isolator with two polarization controllers and the laser produces 966 fs solitonic pulses because the net cavity dispersion is negative.…”
