Abstract

A configuration for linear cavity Brillouin fiber laser (BFL) generation is demonstrated using a standard single-mode fiber, two optical circulators, a $3\mathrm{dB}$ coupler, and a 95/5 coupler to allow high efficiency. With a Brillouin pump (BP) power of $13\mathrm{dBm}$, the laser peak power is $12.3\mathrm{dB}$ higher than a conventional linear cavity BFL at an upshifted wavelength of $0.086\mathrm{nm}$ from the BP wavelength. In addition, it is revealed that the BFL peak power can be higher than the transmitted BP peak power when the BP power exceeds the second Brillouin Stokes threshold power.
