当基束波长调至(3)H(6) ?的最大值时，掺Tm（3+）铝硅酸盐玻璃纤维的二次谐波产生效率提高了10(3)倍。(3)F(4)在785 nm处对Tm（3+）的吸收。这一结果表明共振增强在非线性光学过程中的作用是负责X(2)光栅的形成。
We report a 10(3) increase in efficiency of second-harmonic generation in Tm(3+)-doped aluminosilicate glass fibers when the wavelength of the fundamental beam is tuned to the maximum of the (3)H(6) ? (3)F(4) absorption of Tm(3+) at 785 nm. This result shows the role of resonance enhancement in the nonlinear optical process that is responsible for the formation of the X((2)) grating.
