Extinguishing concentration measurement experiments in the cup burner on two kinds of superfine ammonium phosphate extinguishing agents with different particle sizes had been done by means of filtering and weighing method combined with laser attenuation measurement.

Colloidal silver nanoparticles were prepared by means of laser ablation with 10 ns pulse width laser at 532 nm wavelength in a series of solvents water, ethanol, glycol, etc.

The emphases are laser ablation principle and status quo in fabrication of nano-particle, nano-fibre, nano-thin film.

The optical fiber probe is prepared with the melt-pulling etching,tube etching,pulling-etching and laser ablation method.

Progress in studies of nanoparticle preparation by laser ablation;

Studies on the Theory and Experiment of the Organic Nanoparticle Preparation by Laser Ablation;

Pulsed excimer laser ablation is being extensively applied in chinics to reshape the corneal optical surface of the eye and correct vision defects.

On-line Particle Size Measurement Using Light Extinction;

A new particle monitoring technique of light extinction mode is introduced, of which the principle is based on the fact that when a light beam transmits the flowing suspensions containing suspending particles, different fluctuation degree of transmitted light intensity can indicate the aggregation state of particles.

The spectral light extinction method was developed and applied in wetness and droplet size distribution measurement of high pressure wet steam flow.
