Abstract
- 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.
