This project aims to train participating students in the generation and control of high-order structured laser beams and pulses using solid-state laser platforms. By incorporating nonlinear frequency conversion and cryogenic cooling techniques, we will systematically investigate the spatiotemporal evolution of these structured fields and enhance their power efficiency. The developed laser sources are expected to benefit a range of advanced applications, including precision laser processing, super-resolution microscopy, and quantum communication. Students in this program will gain both theoretical understanding and hands-on experimental experience in laser gain medium and nonlinear crystal design, optical system integration and packaging, as well as low-temperature cooling system implementation. Through this internship, we seek to inspire participating Vietnamese students to pursue further graduate studies (M.S. or Ph.D.) in Taiwan, thereby cultivating future talent in optical and optoelectronic physics and strengthening academic collaboration between Taiwan and Vietnam. -Students who want to apply for the internship should participate at least 2 months. -Students who are in their 3rd or 4th grade and major in Physics will be prioritized as candidates for this internship program. -It is obligatory for the participated student to submit a summary report to review what they have learned during the internship.
