摘要：

Reducing the multiplicity of the orthoexciton ground state in Cu2O by applying uniaxial stress greatly increases the quantum degeneracy of the excitonic gas produced by intense pulsed excitation. Simultaneously, the paraexciton luminescence spectrum develops an extra component at low energy which is interpreted as a Bose-Einstein condensate of paraexcitons.
