报告摘要:

 

Since the discovery of lasers, they have been viewed as promising instruments for producing specific material states by selective manipulations that could not be realized by conventional incoherent addition of thermal or electronic energy to the material. Although the selective laser chemistry is still a dream, the selective control of material processing done by optimization of laser wavelength, pulse duration, pulse energy per unit area and laser average power is frequently used to move some contemporary technology beyond of its limits. The utilization of the unique mid-infrared (IR) laser radiation in hard and soft tissue and in materials research has produced and identified a wealth of high-impact applications and potential technology breakthroughs in these areas. A portable and cost-efficient alternative to the FEL providing high energy/average power tunable mid-IR radiation can be obtained based on all-solid state laser technology. It is potentially used for a number of new emerging technologies e.g. surgery with minimal collateral damage- brain surgery, optic nerve sheath fenestration, mid-IR laser enhanced trans-dermal drug delivery, mid-IR laser induced green fluorescence protein gene transfer and laser induced syntheses of new materials.
