“…The appearance of B-band is at 346 nm while the Q-bands are at 678 and 847 nm. The Q-bands are attributed to π → π * transition energy of the phthalocyanine macrocycle and an excitation state energy [55,59,60]. The sharp peak at 678 nm is related to the crystalline ZnPc particles while the red shift in the Q-bands as specified in the literature is attributed to the clustering of the ZnPc particles inside the film [61,62].…”

A stable mode-locked laser was demonstrated using a newly developed zinc phthalocyanine (ZnPc) thin film as passive saturable absorber (SA) in ytterbium-doped fiber laser (YDFL). The ZnPc thin film was obtained using a casting method and then inserted between the two fiber ferrules of a YDFL ring cavity to generate mode-locked pulses. The resulting pulsed laser operated at a wavelength of 1034.5 nm having a repetition rate of 3.3 MHz. At pump power of 277 mW, the maximum output power and pulse energy are achieved at 4.92 mW and 1.36 nJ, respectively. ZnPc has a high chemical and photochemical stability, and its significance for use as a potential SA in a mode-locked laser is reported in this work. Graphical Abstract
