| 1 | Generation of sub-100 fs pulses tunable from 1700 to 2100 nm from a compact frequency-shifted Er-fiber laser显示文摘We report generation of sub-100 fs pulses tunable from 1700 to 2100 nm via Raman soliton self-frequency shift.The nonlinear shift occurs in a highly nonlinear fiber, which is pumped by an Er-doped fiber laser. The whole system is fully fiberized, without the use of any free-space optics. Thanks to its exceptional simplicity, the setup can be considered as an alternative to mode-locked Tm-and Ho-doped fiber lasers. | GRZEGORZ SOBON TADEUSZ MARTYNKIEN KAROL TARNOWSKI PAWEL MERGO JAROSLAW SOTOR | 2017 | Photonics Research2017，5，3： | 4 |
| 2 | Ultrabroadband wavelength-swept source based on total mode-locking of an Yb:CaF_(2)laser显示文摘We present an ultrabroadband, high-speed wavelength-swept source based on a self-modulated femtosecond oscillator. Photonic crystal fiber was pumped by a mode-locked Yb:CaF2 laser, resulting in a strong spectral broadening from 485 to 1800 nm. The pump laser cavity could be realigned in order to achieve total mode-locking of the longitudinal and transverse TEM00 and TEM01 electromagnetic modes. This led to spatial oscillations of the output beam, which induced modulation of the coupling efficiency to the fiber. Due to the fact that nonlinear spectral broadening was intensity dependent, this mechanism introduced wavelength sweeping at the fiber output. The sweeping rate could be adjusted between 7 and 21.5 MHz by changing the geometry of the pump cavity. By controlling the ratio of the transverse mode amplitudes, we were able to tune the sweeping bandwidth, eventually covering both the 1300 nm and 1700 nm bioimaging transparency windows. When compared with previously demonstrated wavelength-swept sources, our concept offers much broader tunability and higher speed. Moreover,it does not require an additional intensity modulator. | MACIEJ KOWALCZYK TADEUSZ MARTYNKIEN PAWEL MERGO GRZEGORZ SOBON JAROSLAW SOTOR | 2019 | Photonics Research2019，7，2： | 2 |

| 15 | All-in-fiber amplification and compression of coherent frequency-shifted solitons tunable in the 1800–2000 nm range显示文摘We report an all-fiber, all-polarization maintaining(PM) source of widely tunable(1800–2000 nm) ultrashort pulses based on the amplification of coherent self-frequency-shifted solitons generated in a highly nonlinear fiber pumped with an Er-doped fiber laser. The system delivers sub-100 fs pulses with energies up to 8.6 nJ and is built entirely from PM optical fibers, without any free-space optics. The all-fiber alignment-free design significantly increases the suitability of such a source for field deployments. | GRZEGORZ SOBON TADEUSZ MARTYNKIEN DOROTA TOMASZEWSKA KAROL TARNOWSKI PAWEL MERGO JAROSEAW SOTOR | 2018 | Photonics Research2018，6，5： | 1 |
