Abstract:
A dual femtosecond optical frequency comb generation device is provided. The device includes a pump source, a wavelength division multiplexer, a piezoelectric ceramic, an erbium doped fiber, a single mode fiber, a first fiber collimating mirror, a second fiber collimating mirror, and spatial optical path elements, a first quarter-wave plate, a first half-wave plate, a polarization beam splitting prism, an optical isolator, a second half-wave plate and a second quarter-wave plate, and further including a grating pair, the grating pair being composed of a first grating and a second grating and being provided between the polarization beam splitting prism and the optical isolator. The device introduces the light distance difference by using the grating pair, so as to generate dual femtosecond optical frequency combs with a difference in repetition frequency, and the repetition frequency difference can be adjusted by the pitch of the grating pair.

Claim (Index 4):
The dual femtosecond optical frequency comb generation device according to  claim 1 , characterized in that the grating pair ( 10 ) is perpendicular to the direction of light, the first grating ( 15 ) and the second grating ( 16 ) are parallel, the grooved surfaces are opposite to each other and are completely symmetrically placed; the first grating ( 15 ) or the second grating ( 16 ) is fixed onto a precision nano-displacement device.
