A stable mode-locked laser was achieved using a newly developed ZnPc thin film as a passive saturable absorber in a YDFL. The ZnPc film was obtained through casting method and inserted into the YDFL ring cavity, generating mode-locked pulses. The experimental results demonstrate that the pulsed laser exhibits excellent performance with high output power and pulse energy.
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.
