Abstract

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.
