Abstract

An active fiber-optic Fabry–Perot filter with an optical bandwidth adjustable in the 1–100-kHz range for λ = 1088 nm radiation is described. Its bandwidth and peak transmission are stabilized by clamping the loss-compensating gain of the filter to the gain of a nearby laser oscillation. The filter is electronically continuously tunable. Gain is provided by a Nd3+-doped fiber.
