We have generated a bright-dark pulse (BDP) in the passively Q-switched thulium-doped fiber laser (TDFL) with the deployment of 8-Hydroxyquinoline cadmium chloride hydrate (8-HQCdCl2H2O) as an optical modulator in the laser ring cavity. 8-HQCdCl2H2O based thin film was obtained by blending a solutio...
