Abstract

Free-space Brillouin lasers (BLs) are capable of generating high-power, narrow-linewidth laser outputs at specific wavelengths^{[1, 2]}. Although there have been impressive experimental demonstrations of these lasers, there is an absence of a corresponding theory that describes the dynamic processes that occur within them. Understanding the relationship between the cavity parameters and resultant laser characteristics is vital for the design and optimization of these laser systems. The most critical characteristic of a resonantly pumped laser is power enhancement.
