摘要：

Q-switched　Er-doped　all-fiber　laser,　based　on　a　single-walled　carbon　nanotube　saturable　absorber　(SA)　is　constructed.　The　SA　with　a　modulation　depth　of　8%　is　prepared　using　a　special　chemical-corrosion　method.　Furthermore,　the　SA　is　introduced　to　an　Er-doped　all-fiber　laser,　and　Q-switching　is　obtained　successfully.　The　repetition　rate　of　the　Q-switched　laser　can　be　tuned　continuously　from　128　to　278　kHz　with　pulse　widths　from　1.92　μs　to　488　ns.　The　maximum　output　power　is　13.1　mW.　©　2014　Chinese　Optics　Letters.
