“In this study, a successful experiment has been reported on pulse compression in the Q-switched fiber laser by utilizing graphite flakes as a saturable absorber (SA). The sputter deposition method was used to deposited graphite flakes as SA, incorporated into the bore of the laser in order to compress the width of the pulse in the operation of Q-switching. The small repetition rate at 29.6 kHz was mentioned as the maximum power of the pump with the singleto- noise ratio (SNR) ~30dB was required to compress the pulse. Accordingly, graphite flakes have the ability to be utilized as an effective SA in producing pulse compression and Q-switching mode, that will be may fixedly lead to further enhancement in the fiber laser pulsed.”
