Cr ion implantations in glass with the different doses of D=1.493�10<sup>17</sup> and 4.976�10<sup>17</sup> ion/cm<sup>2</sup> are obtained by metal vapor vacuum arc (MEVVA). The effects of the different Cr ion implanted doses on terahertz (THz) transmission property are analyzed from THz time-domain spectroscopy. The results show that the more the Cr ion implanted dose in the micro-area implantation glasses, the larger the THz transmission except the larger absorption at 0.24 THz. This is an effect attributed to the coupling of plasmas on both the implantation and the implantation affected zones of the Cr ion implantation glass.
