摘要: 介绍了一种简便易行的测量光波波长的新方法.测量和研究了汞光及氦氖激光在乙醇(97%)形成的超声光栅中的衍射光谱,并根据氦氖激光的波长,计算了汞光中黄、绿、蓝三色光的波长,并与它们的标准值进行了比较,相对误差分别为0.38%、1.0%、0.60%.

关键词: 超声光栅, 汞光, 氦氖激光

Abstract: A new simple method is proposed for light wavelength measurement.The ultrasonic diffraction spectra of mercury and He-Ne lasers through ethanol solution(97%) are analyzed.Using the He-Ne laser wavelength as the standard value,the wavelengths of yellow light,green light and blue light in mercury are calculated.The relative errors between the calculated and the standard values are 0.38%,1.0% and 0.60%,respectively

Key words: ultrasonic diffraction grating, mercury, He-Ne laser
