Passively Q-switched erbium-doped fiber laser utilizing tungsten oxide as a saturable absorber

We demonstrated a passively Q-switched fiber laser utilizing tungsten oxide (WO3) thin film as a saturable absorber (SA). The WO3-SA was sandwiched as a polymer composite film between fiber ferrules in an erbium-doped fiber cavity. WO3 exhibits high nonlinear optical response characterized by an app...
