Taiwanese and Lithuanian researchers have jointly developed a high-power thin-disk laser (TDL), a milestone that would aid laser development in both countries, National Sun Yat-sen University said yesterday.
The development could also improve Taiwan’s crystalline material production, as well as its laser refining and development capabilities, the university said.
The breakthrough attracted a visit by Lithuanian Laser Association head Gediminas Raciukaitis, who was part of a delegation that traveled to Taiwan earlier this month with Lithuania’s first representative to Taiwan, Paulius Lukauskas.

During the visit, Raciukaitis participated in a demonstration of the TDL, which helped to further Taiwan-Lithuanian collaborations in the field, the university said.
Raciukaitis also toured the university’s optical angular momentum program, led by Department of Materials and Optoelectronic Science professor Lin Yuan-yao (林元堯), and College of Engineering associate dean Chiu Yi-jen’s (邱逸仁) “high-speed silicon photonics and integrated photonics in the semiconductor industry” program.
Lithuania is known for its laser industry and applied uses of laser technology. Raciukaitis’ visit, as well as his suggestions regarding coating and bonding methods, and heat dissipation for the TDL, were greatly appreciated, the university said.
National Sun Yat-sen University materials and optoelectronic science professor Mitch Chou (周明奇) said the TDL is a significant development in high-powered lasers.
Its small size helps with heat dissipation, greatly expanding the applications it can be used for, and its technological threshold is relatively high, Chou said.
The university and Lithuania’s Center for Physical Sciences and Technology earlier this year established the Taiwan and Lithuania Center for Semiconductor and Materials Science. The new center was developing a laser gain medium that would be considerably smaller than the laser beam diameter.
The university has signed deals with three top Lithuanian universities, including the University of Vilnius, and is currently the only university in Taiwan participating in the Ministry of Foreign Affairs’ “Taiwan-Lithuania Semiconductor Talent and Research Scholarship Fund” program.
Six students are studying in Lithuania as part of the program this year, with four Lithuanian students coming to Taiwan, it said.
ANOTHER EMERGES: The CWA yesterday said this year’s fourth storm of the typhoon season had formed in the South China Sea, but was not expected to affect Taiwan Tropical Storm Gaemi has intensified slightly as it heads toward Taiwan, where it is expected to affect the country in the coming days, the Central Weather Administration (CWA) said yesterday. As of 8am yesterday, the 120km-radius storm was 800km southeast of Oluanpi (鵝鑾鼻), Taiwan’s southernmost tip, moving at 9kph northwest, the agency said. A sea warning for Gaemi could be issued tonight at the earliest, it said, adding that the storm is projected to be closest to Taiwan on Wednesday or Thursday. Gaemi’s potential effect on Taiwan remains unclear, as that would depend on its direction, radius and intensity, forecasters said. Former Weather Forecast
As COVID-19 cases in Japan have been increasing for 10 consecutive weeks, people should get vaccinated before visiting the nation, the Centers for Disease Control (CDC) said. The centers reported 773 hospitalizations and 124 deaths related to COVID-19 in Taiwan last week. CDC Epidemic Intelligence Center Director Guo Hung-wei (郭宏偉) on Tuesday said the number of weekly COVID-19 cases reported in Japan has been increasing since mid-May and surpassed 55,000 cases from July 8 to July 14. The average number of COVID-19 patients at Japan’s healthcare facilities that week was also 1.39 times that of the week before and KP.3 is the dominant
The Chinese Communist Party’s (CCP) working group for Taiwan-related policies is likely to be upgraded to a committee-level body, a report commissioned by the Mainland Affairs Council (MAC) said. As Chinese President Xi Jinping (習近平) is increasingly likely to upgrade the CCP’s Central Leading Group for Taiwan Affairs, Taiwanese authorities should prepare by researching Xi and the CCP, the report said. At the third plenary session of the 20th Central Committee of the CCP, which ended on Thursday last week, the party set a target of 2029 for the completion of some tasks, meaning that Xi is likely preparing to
US-CHINA TRADE DISPUTE: Despite Beijing’s offer of preferential treatment, the lure of China has dimmed as Taiwanese and international investors move out Japan and the US have become the favored destinations for Taiwanese graduates as China’s attraction has waned over the years, the Ministry of Labor said. According to the ministry’s latest income and employment advisory published this month, 3,215 Taiwanese university graduates from the class of 2020 went to Japan, surpassing for the first time the 2,881 graduates who went to China. A total of 2,300 graduates from the class of 2021 went to the US, compared with the 2,262 who went to China, the document showed. The trend continued for the class of 2023, of whom 1,460 went to Japan, 1,334 went to
