摘要
采用自行设计组装的激光倍频实验装置,把波长为1 064nm的激光倍频后得到532nm的绿光,并且采集倍频后的光强分布,研究了在不同缝宽的条件下绿光的光强分布。实验结果表明,狭缝的缝宽显著影响光强分布,缝宽越宽,光强越强。利用Matlab软件模拟了二维和三维光强分布图,对激光倍频有了一个更为直观的认识,模拟结果与理论研究相符。
The low wavelength by using laser frequency doubling technology. The equipment used in this work is self-designed which could change the laser wavelength from 1064 nm to 532 nm. The laser intensity distribution is collected. This article studies and compares , the laser frequency doubling of light intensity distribution in the case of different slit width. The results confirm that the slit width affects the intensity distribution ,and the high intensity is received under the condition of different wide slits. Two-dimensional and three-dimensional laser intensity distributions are simulated by Matlab ,which provides a more intuitive understanding of the laser frequency doubling ,and the simulation is agreement with the theoretical study .
