A passively switchable erbium-doped fiber laser based on alcohol as the saturable absorber[SA]has been demonstrated.The SA is prepared by filling the gap between two optical patch cords with alcohol to form a sandwich structure.The modulation depth of the alcohol-SA is measured to be 6.4％.By appropriately adjusting the pump power and the polarization state in the cavity,three kinds of mode-locked pulse patterns can be achieved and switched,including bright pulse,bright/dark soliton pair,and dark pulse.These different soliton emissions all operate at the fundamental frequency state,with a repetition rate of 20.05 MHz and a central wavelength of～1563 nm.To the best of our knowledge,this is the first dem-onstration of a switchable soliton fiber laser using alcohol as the SA.The experimental results further indicate that organic liquid-like alcohol has great potential for constructing ultrafast lasers.
