Our scheme is highlighted by the metal-free and bare-hand manageable process. The sticker is attached onto the flat surface of a D-shaped fiber to demonstrate an efficient fiber mode-locked laser. The 1-ps output pluses have the center wavelength, spectral width, and repetition rate of 1558.2 nm, 5.42 nm, and 4.77 MHz, respectively.
