**2.1. Configuration of the Q-switched TYDFL**

The schematic of the proposed Q-switched TYDFL is shown in **Figure 9**. It is constructed using a simple ring cavity, in which a 15-m long laboratory made TYDF is used for the active medium. An indigenously developed MWCNT-PVA-based SA was used as a Q-switcher. The double clad TYDF was forward pumped by a 905-nm multi-mode laser diode via a MMC.
