Abstract
We experimentally demonstrate a practical and simple method for the preparation of a graphite-based, fiberized saturable absorber (SA). Our SA is prepared by using a low-cost graphite-core pencil that is commercially available from stationary stores to uniformly shade the flat end of a fiber ferrule. The saturable-absorption performance of the prepared SA was experimentally tested, and the feasibility of using the SA as a passive -switch was investigated through its incorporation into an erbium-doped-fiber ring cavity. The modulation depth of the SA is , and the -switched pulses of a 1.98 μs temporal width were readily obtained at a repetition rate of 46.08 kHz.
