摘要
主要研究了如何利用飞秒激光测量绝对长度。解析和数值计算结果显示当飞秒激光通过理想的法布里-珀罗干涉仪时,利用干涉仪透射最大值可以实现绝对标准长度的测量。据此提出了标准频率与绝对长度一一对应的标准。
A proposal for the measurement of absolute length via using femtosecond laser pulse is presented. Analytical and numerical results show that the absolute length can be obtained from the transmission maximum of femtosecond laser pulse in Fabry-Perot cavity. The one-to-one correspondence between frequency and length is also shown.
