摘要

在光泵浦条件下观测到了量子点阵列的受激发射。从基态(λ≈1.31µm)和两个更高能级(λ≈1.21µm, 1.12µm)观察到发射。放大系数的测量值相当高，可达15 ÷ 17 cm−1。讨论了在有源介质中测量放大系数的方法。

Stimulated emission and amplification coefficient for quantum dots arrays under optical pumping

Stimulated emission from quantum dots arrays has been observed under optical pumping. The emission has been observed from the ground state for electrons (λ ≈ 1.31 µm) and from two higher levels (λ ≈ 1.21 µm, 1.12 µm). The measured values of the amplification coefficient are rather high, up to 15 ÷ 17 cm⁻¹. Procedure of the amplification coefficient measurements in the active media has been discussed.
