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 ...

Pulse forming in an AM mode-locking hybrid TEA-CO2 laser [PDF]
We performed an experimental study on the pulse forming mechanism in an AM mode-locked hybrid TEA-CO2 laser by means of “injection mode-locking”. The results show that bandwidth limited pulses will only be reached within a small - critical - range of ...

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

Graphene Actively Mode‐Locked Lasers [PDF]
AbstractActively mode‐locked lasers offer varying degrees of flexibility for a wider range of applications than their passively modulated counterparts, due to their capability for electrically controlled ultrahigh repetition rate operation. Graphene based electrooptic modulators with unique advantages of broad operation bandwidth and ultrafast speed ...

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

Stable operation of a synchronously pumped colliding-pulse mode-locked ring dye laser [PDF]
Pulses of 100-fsec duration are obtained by synchronous pumping of a colliding-pulse ring dye laser with a mode-locked Ar+-ion laser. Stable operation of the synchronously pumped colliding-pulse mode-locked laser over hours was obtained by a suitable ...

A Mode Locking Theory of the Nyquist Laser
We derive a master equation for a mode-locked Nyquist laser that can emit a sinc function pulse. To derive the master equation, we used a method involving exponential perturbative expressions for gain, loss, and amplitude modulation, and a flat-top optical filter with edge enhancement.
