Abstract
We demonstrated that Gallium Doped Zinc Oxide (Ga:ZnO) nanoparticles (NPs) can operate as saturable absorbers (SAs) in the 2 μm region. Casting and sonochemical methods fabricate Ga:ZnO NPs to form an absorber film. The laser system operates at 1959.42 nm with a 1.32 nm spectral bandwidth. The SA film generated a short pulse width of 1.57 μs with a repetition rate of 44.17 kHz, respectively. The laser system attained saturation intensity and modulation depth of 0.09 MW/cm2 and 22 %. The proposed laser also achieved pulse energy and output power of about 5.7 mW and 129 nJ, respectively. This SA was used for the first time in laser applications, especially in the 2-μm region.
期刊介绍：
Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials.
OPTICAL MATERIALS focuses on:
• Optical Properties of Material Systems;
• The Materials Aspects of Optical Phenomena;
• The Materials Aspects of Devices and Applications.
Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
