High-precision sub-femtosecond optical delay line
The high-precision sub-femtosecond optical delay line is a precision instrument based on optical fiber transmission or optical elements (such as piezoelectric translation stages, roof prisms). Its core function is to control the transmission time delay of optical signals to the sub-femtosecond level (1 femtosecond = 10⁻¹⁵ seconds; sub-femtosecond means less than 1 femtosecond). This precision is equivalent to precisely regulating the optical propagation path at the sub-micron level (<0.3 micrometers) at the speed of light (about 300,000 km/s).
