Passively mode-locked laser at 1 mu m region based on tungsten trioxide (WO3) saturable absorber

Stable and efficient mode-locked operation at 1065 nm was demonstrated using tungsten trioxide (WO3) thin film as a saturable absorber (SA). The WO3 thin film composite was prepared by a low cost and simple method and it has a modulation depth of 20 %. As the SA film was inserted into a Ytterbium-do...
