“…In recent years, all-fiber 980 nm ultrashort pulse lasers have attracted more attention [1][2][3][4][5][6][7][8][9] for a variety of applications. For example, it can be used as the pump source for generating a 490 nm blue laser in ocean communication [10,11], for generating high efficiency ultrafast 1030 nm [12][13][14] and 1550 nm lasers [15][16][17], and for supercontinuum lasers [18][19][20] with the spectrum covering the visible to the mid-infrared region. An Yb 3+ -doped fiber laser passively mode-locked by using saturable absorbers (SAs) was considered as the most effective way to generate an all-fiber 980 nm ultrashort pulse laser.…”

We demonstrated an all-fiber passively mode-locked 980 nm picosecond laser using KP 15 materials as saturable absorbers (SAs). The micron-sized wire-like KP 15 crystals were prepared using a vapor-phase transfer method. The material not only shows excellent optoelectronic properties, such as optical anisotropic and large binding energy, but also longterm stability. By inserting the KP 15 crystals into the ytterbium-doped all-fiber laser cavity, a mode-locked 980 nm laser with a pulse duration of 30 ps, a repetition rate of 15.65 MHz and spectral width of 5.6 nm was achieved for the first time, to the best of our knowledge. In addition, we investigated the long-term stability of the KP 15 -based mode-locked 980 nm laser, and the root-mean-square of the output power of the picosecond pulse was only 1.03% when operating for 4 h. The results indicated that the KP 15 material prepared using a chemical vapor transport method was a promising SA for ultrafast fiber laser generation.

We report on sub-40 fs pulse generation from a Yb:Sc2SiO5 laser pumped by a spatially single-mode fiber-coupled laser diode at 976 nm. A maximum output power of 545 mW was obtained at 1062.6 nm in the continuous-wave regime, corresponding to a slope efficiency of 64% and a laser threshold of 143 mW. A continuous wavelength tuning across 80 nm (1030 -1110 nm) was also achieved. Implementing a SESAM for starting and stabilizing the mode-locked operation, the Yb:Sc2SiO5 laser delivered soliton pulses as short as 38 fs at 1069.5 nm with an average output power of 76 mW at a pulse repetition rate of ∼79.8 MHz. The maximum output power was scaled to 216 mW for slightly longer pulses of 42 fs, which corresponded to a peak power of 56.6 kW and an optical efficiency of 22.7%. To the best of our knowledge, these results represent the shortest pulses ever achieved with any Yb3+-doped rare-earth oxyorthosilicate crystal.

A high-quality Nd0.01:Gd0.89La0.1NbO4 (Nd:GLNO) crystal is grown by the Czochralski method, demonstrating wide absorption and fluorescence spectra and advantage for producing ultrafast laser pulses. In this paper, the tunable and passively mode-locking Nd:GLNO lasers are characterized for the first time. The tuning coverage is 34.87 nm ranging from 1058.05 to 1092.92 nm with a maximum output power of 4.6 W at 1065.29 nm. A stable continuous-wave (CW) passively mode-locking Nd:GLNO laser is achieved at 1065.26 nm, delivering a pulse width of 9.1 ps and a maximum CW mode-locking output power of 0.27 W.
