Grazing-Incidence-Disk Laser Element

Laser systems are widely used in numerous applications such as communications, information processing, and precision engineering. Especially in these fields, there's a growing need for enhanced power gain and optimized signal propagation. Traditional gain elements often struggle to build up an adequate gain or make efficient use of the power of a pump beam. In current designs, pump beam distribution is a persistent issue, frequently leading to wastage and inefficiency. Additionally, with multiple passes through the gain elements, power transfer can become even more challenging. The asymmetric shape of the gain region in most conventional methods is another problematic factor. Therefore, there is an imperative requirement for a suitable technology that could address these issues, thereby enhancing the efficiency of optical technology.

Technology Description

The technology pertains to a solid-state gain element that incorporates a thin doped region for optimized optical signal propagation. In this gain element, both the optical signal and the pump beam navigate through the thin doped region at an acute angle with respect to the normal, offering a more refined propagation trajectory. Furthermore, a unique feature of this design is that there can be total internal reflection of the pump beam, particularly relevant when multiple pumping passes are needed. This technology, by utilizing total internal reflection, markedly differentiates itself from the conventional alternatives. Not only does it offer a more efficient propagation pathway, but it also enables a pump beam to make multiple passes through the thin doped region, thereby significantly enhancing power gain. Another effective aspect is the formation of a circularly symmetrical gain region, brought about by an elliptically symmetrical laser beam. Overall, these unique design features make this technology an advanced solution for diverse optical applications.
