摘要：

We show that the quantum Zeno effect (QZE) plays an essential role in discussions of lasing without inversion (LWI) in a V-level scheme. We investigate this role using Monte Carlo wave-function simulations, which provide insight into the physical origin of inversionless lasing. The QZE appears as a result of spontaneous emission and the corresponding collapse of the wave function. Whereas the usual explanation of LWI in terms of quantum interference requires coherence, the QZE explains why incoherent processes are also needed.
