Pulsed-Laser-Triggered Piezoelectric Photocatalytic CO Reduction over Tetragonal BaTiO Nanocubes.

The recombination of photoinduced carriers in photocatalysts is considered one of the biggest barriers to the increase of photocatalytic efficiency. Piezoelectric photocatalysts open a new route to realize rapid carrier separation by mechanically distorting the lattice of piezoelectric nanocrystals to form a piezoelectric potential within the nanocrystals, generally requiring external force (e.g.

Picosecond dissipative soliton generation from an ytterbium-doped fiber laser based on a BP/SnSe-PVA mixture saturable absorber.

Stable picosecond dissipative soliton pulses were observed in an ytterbium-doped fiber laser employing a high-quality mixture of BP/SnSe-PVA saturable absorber (SA). The modulation depth, saturation intensity, and non-saturable loss of the mixture of BP/SnSe-PVA SA were measured with values of 5.98%, 18.

Generation of High Peak Power Mode-Locked Green Pulses Based on WS and EOM: Experiment and Theory.

Based on an as-prepared high-quality WS film and an electro-optic modulator (EOM), a dual-loss-modulated low repetition rate mode-locking laser at 0.53 μm with high peak power is presented for the first time. The laser characteristics versus the pump power are investigated experimentally and theoretically.
