Coherently pumped micromaser as a maser without inversion

Abstract

In this paper, we use microscopic maser theory developed by Filipovicz, Javanaien and Meystre [Phys. Rev. A 34, 3077 (1986)] to investigate the properties of the coherently pumped two-level micromasers. We find that under right conditions, the initial atomic coherence locks the field phase and unlike ordinary lasers and masers there is no longer threshold. Consequently, the population inversion is not necessary.

Keywords

two-level micromaser; coherent pumping; locking of the field phase; no threshold; population inversion unnecessary
