“…There are several research articles related to solve the problem of fiber coupling a high energy (several mJ) and short pulse (ns) laser. [1][2][3][4] Two main group of variables have significant effect to getting acceptable results in fiber coupling, one is the laser beam profile and the other one is the optical fiber characteristics. Hollow core fibers or photonic-crystal fibers can provide really good results, [5][6][7] but because our aim is to develop a system with reasonable price we had to use commercially available multi-mode silica fibers.…”

For several spectroscopy applications, there is a high demand for the small and economical fiber-coupled highpower laser system. In our case, a high-energy DPSS laser pulse was delivered by an optical fiber. For the reason of cost efficiency, we used commercially available "off the shelf" components, like pump diodes, multimode optical fibers and 3D printed components. In this case, the challenge is that the focused high-energy laser pulses can easily damage the optical fiber. To avoid this problem, we redesigned the entire laser cavity structure, optimizing the laser beam characteristics that fit a special fiber coupling module. In this work, we are presenting the development of a compact, low-price, high-energy Q-Switched Nd:YAG laser with a directly connected optical fiber using commercially available components.
