The generation of pulsed laser output can be done in two ways which are Qswitching and mode-locking technique [1-3]. Mode-locked fiber lasers are preferable for the applications that require pulses in the megahertz (MHz) range, however Q-switched fiber lasers attract the applications that require slower pulse rate but higher output powers [4-8]. Mode locking technique can be done either in active or passive ways but the passive method gains so much research interest as the technique is more compact and low cost [9]. To generate mode locked pulses in the passive way, the saturable absorber (SA) plays an important role to provide the mechanism within an efficient low cost system [10]. In the early days, passive mode locking is typically done by using semiconductor saturable absorption mirrors (SESAMs) but they are bulk in size, complex and relatively high cost [11]. Passively mode-locked fiber laser is known to be the most efficient technique in achieving high pulse energy. Thus, optical fibers are the excellent components that consist in fiber laser which are most stable, compact, low-loss, practical laser and have unlimited bandwidth.
