随着可调谐染料激光技术的发展,激光光谱工作需要精度更高、测量更简捷的激光波长计。一般激光光谱精度大致为1GH_2或10~(-6)。激光波长计分为静态和动态二大类,静态波长计将干涉条纹同时以许多落在多个探测器上,它可以测量连续的或脉冲的激光波长。动态波长计需要在一段时间内采集干涉条纹数据,因此,它只能用来测量连续激光的波长。
With the development of tunable dye laser technology, laser spectroscopy work requires more accurate and simpler measurement of the laser wavelength meter. General laser spectral accuracy of roughly 1GH_2 or 10 ~ (-6). Laser wavelength is divided into static and dynamic two categories, static wavelength meter interference fringes will fall on many detectors at the same time, it can measure the continuous or pulsed laser wavelength. The dynamic wavelength meter needs to collect the interference fringe data over a period of time, so it can only be used to measure the wavelength of a continuous laser.
