Generation of Q-switched fiber laser at 1.0-, 1.55-and 2.0-mu m employing a spent coffee ground based saturable absorber
Spent coffee ground (SCG) was demonstrated as saturable absorber (SA) for Wideband Q-switched fiber lasers generation. The SCG SA has a broad linear absorption that covers from 1000 nm to 2000 nm wavelength and a modulation depth of 30% at 1.55-mu m region. Through purification process, the finer SC...
