NOT KNOWN FACTUAL STATEMENTS ABOUT CO²�?/ZNS CRYSTAL

The modulation depth could be tuned in a broad vary from 66.5% to six.2% by different the thickness of graphene. Our success recommend that ultrathin graphene movies are probably useful as optical factors in fiber lasers. Graphene as a laser mode locker might have lots of merits including decrease saturation depth, ultrafast recovery time, tunable
