Such a laser produces a supercontinuum light, which is composed of a cluster of coherent frequency components in certain interval of wavelengths. A value of the repetition rate (frequency) of femtosecond pulses determines (in the frequency domain) spacing of these coherent components. If we control the mode-lock laser by means of i.e. atomic clocks we ensure frequency of these components very stable. The comb spectrum plays a role as a frequency rule which is suitable for the metrology of length in various branches: it can be used as a tool for generation of precise distance and at the same time as a length measuring device with the atomic clock as the fundamental reference."@en . .
