Claim:
1. A low-loss high-repetition-rate pulsed laser modulator comprising: two 1*2, 1:1 couplers configured as an input end and an output end of the modulator respectively; at least two light delay modules arranged on a same light path between the two 1*2, 1:1 couplers; and at least one 2*2, 1:1 coupler with each arranged between two adjacent light delay modules; wherein the light delay modules are configured to control path-length difference Δl according to the following formula: where, c is a velocity of light in vacuum, n is a refractive index of fibers, k is a natural number, and t is time difference between two neighboring pulses respectively transmitted in two light paths.
