摘　　要：使用一种可调谐双频TEA CO2激光器输出的空间重叠的双频CO2激光对BC l3进行多光子离解,在没有聚焦的情况下照射反应池中BC l3和O2的混合气体150次,生成物(B2O3)中10B的富集系数达到1.80。A kind of dual-wavelength tunable TEA CO2 laser, which can produce dual-wavelength laser pulse and in the laser pulse the two optical fields overlap partially in the space, is used in the experiment of isotope separation of boron by multiphoton. The laser pulse irradiated the mixtures of BC13 and O2 in the reactive pool 150 times without being focused on. The enrichment coefficient of ^10B reached 1.80 in the product（ B2O3 ）.
