Embodiment Construction
[0027] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.
[0028] Such as figure 1 As shown, the measurement system of the present invention includes a tunable laser light source system based on an optical frequency comb reference and an interferometric optical path system. It specifically includes femtosecond optical frequency comb 1, high-precision wavelength meter 2, external cavity semiconductor tunable laser 3, beat frequency detection and locking feedback module 4, pinhole filter 5, reference plane 6, imaging lens group 7 and CCD 8.
[0029]Femtosecond Optical Frequency Comb 1 is a fully stable femtosecond pulsed mode-locked laser. The laser corresponds to a series of frequencies arranged at equal intervals in the frequency domain. Because its shape is similar to a comb, it is also called an optical frequency comb. The frequency corresponding to each comb tooth is determined by the repetition f...
