摘要

Recently, with the precise laser interferometers the LIGO-Virgo collaboration [1-4] has realized the direct detection of the GWs, by probing their minute mechanical displacements. The peak strains of the detected GWs are at the order of 10?21 and their frequencies are in the low- and intermediate frequency band, i.e., dozens and hundreds of Hertz. Given the GWs could exist at any frequency [5, 6], in principle, probing the GWs in the wider bands [7, 8], typically the high frequency GWs expected by a series of models for cosmology and high-energy astrophysical processes [9-12], is still a challenge [13].
