Abstract
Provided is single-walled carbon nanotube saturable absorber production via a multi-vacuum filtration method, and more particularly, single-walled carbon nanotube saturable absorber production via a multi-vacuum filtration method, capable of depositing a carbon nanotube thin film on a filter using a vacuum chamber and a membrane filter, etching the filter using an etchant so as to be transferred to an upper surface of the polymer, coating the polymer on the carbon nanotube to thereby produce a carbon nanotube saturable absorber, as a method of producing a carbon nanotube thin film to transfer the thin film to the polymer using a multi-filtration method in order to produce a passive saturable absorber to be used in laser oscillation.
