We report an all-polarization-maintaining figure-9 mode-locked Er-doped fiber laser based on a nonlinear amplifying loop mirror with in-loop active phase modulation. The laser can be stably mode-locked at 10 GHz to produce ps optical pulses. The laser is also environmentally stable due to its all-polarization-maintaining fiber cavity design.

 

A dominant mode hopping in collective lasing was observed experimentally under different temperature condition. We excited a InGaN-based core–shell nanorod array from T=300K to 195 K by photoluminescence. Theoretical simulation was performed to show the difference of the carrier dynamics and the gain spectrum in core and shell structure.

 

A silica-coated inorganic perovskite quantum dot hybrid light-emitting diodes is aged continuously in high and low light intensity conditions. Both blue and ultra-violet-pumped samples showed stable performances up to 104 hours.

 

The Drude–Lorentz model was used to describe graphene and analyze its charge transfer effect with regard to the performance of aluminum-based plasmonic nanolasers. The variation in charge density influenced the optical properties of aluminum and demonstrated the effect of charge transfer on the characteristics of surface-plasmon-polariton (SPP) modes.

 

Diode-pumped EO Q-switched Tm:YAP laser was constructed by a cascaded dual MgO:PPLN crystal. When diode pump power was 18 W, the pulse energy, pulse duration and repetition were 2.46 mJ, 64 ns and 200 Hz, respectively. Output wavelength can be selected between 1940 and 1990 nm when changing output coupling.

 

For the first time periodic II, periodic VI and aperiodic oscillation dynamics are reported in passive Q-switched vortex lasers employing azimuthal symmetry breaking resonator configuration supporting multiple pass transverse modes which suggest the route to chaos in the proposed laser system.

 

We develop a new method for numerically analyzing general mode-locked laser noise problems based on the linearized back-propagation approach. The timing jitter and relative intensity noise properties of hybrid mode-locked fiber lasers with active amplitude/phase modulation are examined for demonstrating the effectiveness of the proposed method.
