Title :
Saturable absorption in a tapered single-mode optical fibre
Abstract :
A novel all-fibre saturable absorber based on the interaction between the evanescent field of a tapered single-mode fibre and a surrounding solution of a laser dye is described. Results are presented which demonstrate saturable absorption at pump powers of only tens of milliwatts.
