We present a novel method for heightening the sensitivity.of a prism coupler-based surface plasmon resonance(SPR)*** method is based on the total reflection prism made of BK7 glass combined with the Kretschmann geometry.of theattenuated total reflection(ATR)*** to the conventional methods of prism coupler-based SPR,the novel method provides higher sensitivity.to the measurement *** simulations show that the detection sensitivity.to the refractive index(RI)of the sensor based on the novel approach has a strong dependence on the thickness of the metal *** RI resolution of the sensor is predicted to be 8×10^(-7)refractive index units(RIU)under the condition of optimum metal film *** novel method can leave out a precision angle rotation device in the angle modulation and it is unnecessary.to adjust the acceptance angle of the light *** principal advantage of this method over other methods of light intensity.modulation based on prism coupler-based SPR is high sensitivity.expediency.to measure and application of long distances.

Considering the atmospheric extinction and turbulence effects,we investigate the propagation performances of supercontinuum laser sources in atmospheric turbulence statistically.by.using the numerical simulation method,and the differences in propagation properties between the super-continuum(SC)laser and its pump laser are also *** is found that the propagation characteristics of super-continuum laser are almost similar to those of the pump *** degradation of source coherence degree may.cause the relative beam spreading and scintillation indexes to decrease at different propagation distances or different turbulence *** root-mean-square value of beam wandering is insensitive to the variation of source correlation length,and less aperture averaging occurs when the laser source becomes less ***,from the point of view of beam wandering,the SC laser has no advantage over the pump *** the pump laser can bring about a bigger aperture average,the SC laser has a lower scintillation which may.be due to the multiple wavelength homogenization effects on intensity.*** would be the most important virtue of the SC laser that can be utilized to improve the performance of laser engineering.
