Abstract:
The effects of spectral broadenings of laser materials on laser frequency pulling are compared,and the spectra and the characteristics of output from an ultrashort cavity dye laser (SCDL) at multi-longitudinal mode (LM) states were measured and observed experimentally.The instantaneous cavity length of SCDL can be determined by measuring the curves of the LM spacing vs the middle wavelength of the adjacent LM.

Abstract:
Ultrafine particle (UFP) is a new material,which developed rapidly in recent years.The UFP has many special properties,and will play an important role in science and technology facing the 21st century.In the present paper,the principles,devices,characteristics and present situation of producing ultrafine particles by the laser vapor-phase reaction,the laser heating gas-evaporation,the infrared multiple-photon decomposition,and so on,are reviewed.The laser making technology of ultrafine particles is expected to have the possibility of wide applications in the future.

Abstract:
Using the rate equations,we derive expression for Q-switched Nd:YAG laser efferency,which is related to the system parameters.The performance of a Q-switched laser can be optimized through proper choice of output mirror reflectivity.A simple process for Q-switched laser efferency is presented.
