Abstract
The article describes the stages of obtaining an absorbing medium based on multilayer graphene in a matrix of carboxymethyl cellulose on an optical substrate. The results of the analysis of the obtained graphene - carboxymethyl cellulose medium are presented. A possible variant of testing the absorbing - saturating properties of the working environment is described.
Highlights
Today, passive mode locking [1] is used to obtain ultra short pulses in femtosecond fiber laser systems
Particles were separated and a graphene layer was separated in a carboxymethyl cellulose polymer medium by centrifugation under the influence of ultrasound
The result was a suspension of graphene in carboxymethyl cellulose (SAG)
Summary
Passive mode locking [1] is used to obtain ultra short pulses in femtosecond fiber laser systems. Often this mode is provided by SESAM absorbers [2], which have a relatively high cost. Absorbers on carbon-containing structures can be compared with SESAM modulators in parameters. Their development consists in applying a material layer of a few micrometers thick at the base of the optical element. In this case, as a working material, multilayer graphene structures can be used
