We demonstrate a novel method of ring cavity Q-switched pulse erbium-doped fiber laser (EDFL) for liquid ammonia sensors. Q-switched pulse is generated using an indium tin oxide (ITO) deposited onto a side-polished fiber (SPF) as a saturable absorber (SA). The generated Q-switched pulses exhibit a r...
