Highly stable MXene (V2CTx)-based harmonic pulse generation
MXene as a novel two-dimensional (2D) material exhibits a lot of advantages in nonlinear optics. However, the common MXene, Ti3C2Tx and Ti2CTx nanosheets, easily suffer from degradation under ambient conditions, greatly limiting their practical ...

Recent progress in passively mode-locked fiber lasers based on low dimensional nanomaterials
Passively mode-locked fiber lasers have applications in industry, optical communication, biology, chemistry and so on. Saturable absorber (SA) is a key component in mode-locked fiber laser that can periodically modulates the intra-cavity laser pulses and

Kerr-Lens Mode-locked Cr:ZnS Laser [PDF]
We report the soft-aperture Kerr-lens mode-locked Cr:ZnS laser, generating 550 mW of 69 fs nearly transform-limited pulses at 2.39 μm wavelength. The pulse energy reached 3.8 nJ at 145 MHz repetition rate, limited by the onset of double-pulsing. This corresponds to the shortest-pulse and highest-energy direct femtosecond laser source in the mid ...

860 femtoseconds mode-locked fiber laser by Gallium co-doped erbium fiber (Ga-EDF)
We proposed and demonstrated a high power mode-locked fiber laser using a new type of gain medium which is called as Erbium Gallium co-doped fiber (Ga-EDF). The mode-locking mechanism is enabled by a graphene-based saturable absorber, which is fabricated

Mode-locked lasers are the fundamental source of ultrashort and ultraintense light pulses and a principal pathway for three Nobel Prize technologies: optical frequency combs, chirped pulse amplification, and attosecond light pulses. They are essential in routine and high-level applications such as refractive surgery, spectroscopy, or metrology.

Mode-locked silicon evanescent lasers
We demonstrate electrically pumped lasers on silicon that produce pulses at repetition rates up to 40 GHz. The mode locked lasers generate 4 ps pulses with low jitter and extinction ratios above 18 dB, making them suitable for data and telecommunication transmitters and for clock generation and distribution.
