Abstract
The potential for substantial threshold reduction in stimulated Brillouin scatter phase conjugate mirrors (PCMs) was systematically studied using tapered hollow glass waveguides filled with carbon disulfide. Using a low-threshold PCM of 100 cm straight section length and 10 μm inner diameter, the threshold was reduced by a factor of 1000 compared to the bulk liquid threshold. Use of a tapered input alleviated alignment sensitivity normally encountered with small-input-diameter fibers, and allowed for the fabrication of wide-field-of-view PCMs (and Brillouin amplifiers) of a type useful in many applications. Performance of the low-threshold PCM was found to meet theoretical expectations.
