A high-stability wavelength-tunable single-frequency (SF) ytterbium-doped all-fiber compound ring laser has been demonstrated experimentally. The compound ring cavity is composed of a fiber optical tunable filter, a high-finesse ring filter, and a loop mirror filter. Three segments of ytterbium-doped fibers are employed as the gain medium or saturable absorber, respectively. The SF operation is observed...
We present results of our research on the observation of a bound state of double dissipative-soliton operation of a passive mode-locked Yb-doped fiber laser based on the nonlinear polarization rotation mechanism through the proper adjustment of the wave plates. The generated dissipative solitons with large net positive cavity Group Velocity Dispersion (GVD) are characterized by their spectral profile...
We realized an Yb-fiber laser comb with spaced modeline of larger than 20 GHz, the side-mode was suppressed to 40 dB by two low-finesse Fabry-Pérot cavities. Long term stabilization was demonstrated by locking cavity lengths.
We have realized locking of external cavity diode laser to a vibration-insensitive high finesse Fabry-Perot cavity using PDH technique. Linewidth to 1MHz was obtained at 243nm by enhanced frequency-doubled second harmonic of diode laser.
