چکیده
We report a passively dual-wavelength mode-locked Yb:LuYSiO5 (Yb:LYSO) laser with a double-walled carbon nanotube saturable absorber (DWCNT-SA) for the first time. Simultaneous mode-locking at the 1045.5 and 1059.0 nm was achieved and the pulse duration of the dual-wavelength modelocked pulses are 8.0 ps. Ultrahigh repetition rate ultrafast pulses with 750 fs pulse width and 3.66 THz repetition rate were further obtained. The average output power of 1.27 W with a repetition rate of 103.5 MHz was obtained using absorbed pump power of 12.83 W and the slope efficiency is 13.0%.

Single-walled carbon nanotube saturable absorber assisted high-power mode-locking of a Ti:sapphire laser.
We report on passive mode-locking of a Ti:sapphire laser employing a single-walled carbon nanotube saturable absorber (SWCNT-SA) specially designed and fabricated for wavelengths near 800 nm. Mode-locked pulses as short as 62 fs were generated at a repetition rate of 99.4 MHz. We achieved output powers from the SWCNT-SA mode-locked laser as high as 600 mW with a slope efficiency of 26%. The cha...

متن کاملWideband-tuneable, nanotube mode-locked, fibre laser.
Ultrashort-pulse lasers with spectral tuning capability have widespread applications in fields such as spectroscopy, biomedical research and telecommunications. Mode-locked fibre lasers are convenient and powerful sources of ultrashort pulses, and the inclusion of a broadband saturable absorber as a passive optical switch inside the laser cavity may offer tuneability over a range of wavelengths...
متن کاملNanosecond soliton pulse generation by mode-locked erbium-doped fiber laser using single-walled carbon-nanotube-based saturable absorber.
We demonstrate a simple and low cost mode-locked erbium-doped fiber laser (EDFL) operating in the nanosecond region using a single-walled carbon nanotube (SWCNT)-based saturable absorber (SA). A droplet of SWCNT solution is applied on the end of a fiber ferrule, which is then mated to another clean connector ferrule to construct an SA. Then the SA is integrated into a ring EDFL cavity for nanos...

We demonstrate passive mode-locking of a Tm,Ho-codoped crystalline laser operating on the Ho³⁺-ion transition ⁵I₇→⁵I₈ near 2 µm using a single-walled carbon nanotube saturable absorber. The Tm,Ho:KLu(WO₄)₂ laser emits nearly transform-limited pulses with duration of 2.8 ps at a repetition rate of 91 MHz. The output power amounts to 97 mW.
