NOT KNOWN FACTS ABOUT CO²�?/ZNS CRYSTAL

The modulation depth might be tuned in a large range between 66.5% to six.2% by varying the thickness of graphene. Our results propose that ultrathin graphene films are possibly useful as optical factors in fiber lasers. Graphene as a laser mode locker may have lots of deserves such as reduced saturation intensity, ultrafast Restoration time, tunab
