| description | Many materials have been utilized as saturable absorbers in generating pulsed lasers.
By incorporating them with host polymers such as polymethylmethacrylate (PMMA), polyvinyl
alcohol (PVA) and polyethylene oxide (PEO), the process of saturable absorber integration into
the laser cavity is made easier. This work reported the generation of Q-switched pulsed lasers
based on graphene embedded in chitin saturable absorber. Graphene: chitin with a concentration
of 1:1 and 1.5:1 are integrated into a fiber laser cavity and the laser performance of both SAs are
recorded and compared. The graphene chitin SA of 1:1 concentration produces a higher
repetition rate and shorter pulse duration of 111.77 kHz and 1.328 μs, respectively. However,
the SA with higher graphene content operated at a larger range of input pump power yielding a
higher instantaneous peak power and pulse energy of 7.29 mW, and 14.37 nJ, respectively. This
work introduces chitin as a potentially excellent natural host polymer as an alternative to
conventional ones such as polyvinyl alcohol (PVA) and polyethylene oxide (PEO). |
